The computer room was quite deserted, with not a single person in sight.
It has to be said that it makes sense for other people's Windows systems to occupy such a large market share. Even a novice who has never touched a computer can easily get started with a full-graphics operating system.
And he only has less than 10,000 yuan in his card, so it might be difficult for him to even light a small flame.
"Although the book explains it very clearly, I didn't expect it to be so troublesome to use... As expected, what's on paper and actual operation are completely different things. If you want to learn something, you still have to practice it."
Lu Zhou, who was using the Linux system for the first time, felt blind. He followed the tutorial borrowed from the library for a long time before he finally figured out the ropes.
After all, it’s summer vacation right now, and those taking the postgraduate entrance examination generally don’t have access to computers.
When he thought of this, Lu Zhou stopped dawdling and started working immediately.
Immediately afterwards, the fan of the chassis began to buzz, and the computer became laggy. Lines of code flashed from the black dialog box and were quickly organized into tables.
"The first is to automatically grab tickets. This should not be considered an innovation. Cheetah and 360 browsers already had this function a long time ago."
Although there are many third-party ticket booking APPs on the Internet, there is really no official ticket booking APP. If he could make something unique and sell it to interested operators, he might be able to earn some living expenses.
After saving the word document, Lu Zhou rolled up his sleeves enthusiastically and put his hands on the keyboard.
Looking at the train data piling up in the folder, Lu Zhou rolled his eyes, wondering if he should use it for something
It seems quite boring.
After walking over and turning on the air conditioner, Lu Zhou found a computer and sat down. He entered his student ID and password and logged into the computer skillfully.

As soon as this impromptu idea emerged, it took root and sprouted in his heart uncontrollably.
"When it comes to one of the applications of Python is to write web crawlers. If you want to test your learning results, this is the best place to start... But what kind of crawler should you make?"
Thinking of this, Lu Zhou looked up at the wall clock.
or…
The reason why I chose the computer room of the school is mainly because the programs written in python language are mainly run under the Linux system. Learning python language directly in the Linux environment can be said to kill two birds with one stone.
As soon as this impromptu idea emerged, it took root and sprouted in his heart uncontrollably.
By constantly refreshing the official website data, there is a certain metaphysical probability that some tickets will be generated. Some of them are refunds from other users. Some of them are not sure how Lu Zhou came out, but this function can be considered.
Copying the URL of the website behind the code, Lu Zhou chose to run it, generated a table from the data, and imported it into the pre-built folder.

It’s just that it may cost a lot of money to purchase and maintain a server. The electricity bills and various maintenance costs for operating the server may also be a big expense...
Lu Zhou's own second-hand notebook was really rubbish. He had to pretend to be dead for a while to convert the paper into PDF format. He didn't get online until other people started to play online. There was no need to install dual systems or virtual machines and other cumbersome operations. Thought.
Of course, 12306 is not an ordinary BBS forum after all. It is still quite difficult to use this as a practice target for beginners.
"Building a ticket booking website? It seems like someone took off his pants and farted..."
After becoming familiar with the basic operations of the Linux system, Lu Zhou opened the python software, opened the book, and sat in front of the computer in a daze.

Therefore, many "stingy" websites will be equipped with anti-crawler programs. The more technical ones will either prevent you from crawling anything, or the crawled ones will be garbled. The less technical ones can also be directly locked by monitoring the number of visits. your IP.

After all, as a typical application example of python language, the templates of crawler programs are mentioned in the book, and the algorithm is improved to varying degrees in the book for different situations.

Therefore, Lu Zhou closed the program and did not rush to change the code. Instead, he opened the word document and began to design the outline of the APP development process just like writing the outline of a paper.
But it's just a big deal. For Lu Xueba, who has already read the entire book, it's not a big problem. The crawler itself is not too technically difficult. The entire program can be completed in less than 30 lines of code, and it runs perfectly without bugs.
It has to be said that it makes sense for other people's Windows systems to occupy such a large market share. Even a novice who has never touched a computer can easily get started with a full-graphics operating system.
Of course, 12306 is not an ordinary BBS forum after all. It is still quite difficult to use this as a practice target for beginners.
But of course, it's just an illusion, not even a feeling. After all, this thing has nothing to do with hacking technology. It is not illegal to crawl public information from the server. At most, it is suspected of occupying other people's server resources, which will be hated by major webmasters.

"When it comes to one of the applications of Python is to write web crawlers. If you want to test your learning results, this is the best place to start... But what kind of crawler should you make?"
However, the Linux system is different. It is basically a command line operation mode, and all operations can be completed through the keyboard. Fortunately, the school installed a distribution with a desktop environment, otherwise Lu Zhou would not have known the use of a mouse.
The key is that the data you climbed down is useless in your hands. There is too much data and there is no place to put it.
Then comes the grabbing.
Of course, the advantages of Linux are also obvious. Its super customizability and security make it more suitable for servers and other fields than Windows systems. And once you are familiar with command line operations, the efficiency will be several times higher than that of Windows system. Therefore, when many companies recruit server front-end and back-end programmers, they will ask whether they can use the Linux system.
Thinking of this, Lu Zhou looked up at the wall clock.
For example, set a time period and several trains, and the server will automatically refresh the data for the user, and submit the order the moment the remaining tickets appear. It seems that among the several ticket-grabbing software he has seen so far, this function is not available.
It's 3pm now!

Thinking of this, Lu Zhou looked up at the wall clock.
However, the 12306 website is obviously not that stingy. Think about it, a monopoly giant that doesn’t even care about user experience, would it care about server resources? As long as you don't mess with my server, who cares about you!

Even if you fail, it doesn't matter if you just do the lessons and practice your skills.
The computer room was quite deserted, with not a single person in sight.
Looking at the rows of data flashing past, Lu Zhou really had the illusion that he was addicted to hacking.
"When it comes to one of the applications of Python is to write web crawlers. If you want to test your learning results, this is the best place to start... But what kind of crawler should you make?"
Technically, it is very difficult to independently develop an APP from front-end to back-end. It is far more difficult than writing a simple crawler program, but it is not impossible to complete. What's more, if the algorithm can't solve it, you can still ask the system. Spending points to query data is also a learning process in itself.
"Train ticket query must crawl real-time data, which requires very high performance of the server, and the code must be as concise as possible!"

"But the ticket will automatically be swiped when you hang up... I haven't seen it before." Thinking about last year's winter vacation, when the tickets were booked late, a few animals in the dormitory sat in front of the computer and pressed F5 for almost half an hour before they swiped out a few tickets. After Zhang Zhang's return ticket, Lu Zhou deeply felt that it was not easy for the working people to return home during the New Year.
Suddenly, something moved in his heart, and he somehow recalled the painful experience of grabbing tickets every time he went home. It’s not because his computer is stuck, but because the UI design of the Ministry of Railways’ official website is so anti-human.

"When it comes to one of the applications of Python is to write web crawlers. If you want to test your learning results, this is the best place to start... But what kind of crawler should you make?"
It's 3pm now!
Looking at the rows of data flashing past, Lu Zhou really had the illusion that he was addicted to hacking.
As he wrote this, Lu Zhou gently rubbed the keyboard with his index finger. He thought for a long time before continuing to type on the keyboard.
Although there are many third-party ticket booking APPs on the Internet, there is really no official ticket booking APP. If he could make something unique and sell it to interested operators, he might be able to earn some living expenses.
"Train ticket query must crawl real-time data, which requires very high performance of the server, and the code must be as concise as possible!"
As soon as this impromptu idea emerged, it took root and sprouted in his heart uncontrollably.
Suddenly, Lu Zhou's heart moved.
As he wrote this, Lu Zhou gently rubbed the keyboard with his index finger. He thought for a long time before continuing to type on the keyboard.
Technically, it is very difficult to independently develop an APP from front-end to back-end. It is far more difficult than writing a simple crawler program, but it is not impossible to complete. What's more, if the algorithm can't solve it, you can still ask the system. Spending points to query data is also a learning process in itself.
"Start working!"
"Although the book explains it very clearly, I didn't expect it to be so troublesome to use... As expected, what's on paper and actual operation are completely different things. If you want to learn something, you still have to practice it."
Make an APP for online ticket booking
When it came to the issue of money, Lu Zhou immediately became concerned and began to make calculations in his mind.
Therefore, Lu Zhou closed the program and did not rush to change the code. Instead, he opened the word document and began to design the outline of the APP development process just like writing the outline of a paper.
By constantly refreshing the official website data, there is a certain metaphysical probability that some tickets will be generated. Some of them are refunds from other users. Some of them are not sure how Lu Zhou came out, but this function can be considered.
However, the Linux system is different. It is basically a command line operation mode, and all operations can be completed through the keyboard. Fortunately, the school installed a distribution with a desktop environment, otherwise Lu Zhou would not have known the use of a mouse.
"Use crawler technology to crawl the 12306 website's station, train number, and remaining ticket data information... This seems to be possible."

Even if you fail, it doesn't matter if you just do the lessons and practice your skills.
It has to be said that it makes sense for other people's Windows systems to occupy such a large market share. Even a novice who has never touched a computer can easily get started with a full-graphics operating system.
"Building a ticket booking website? It seems like someone took off his pants and farted..."
After all, as a typical application example of python language, the templates of crawler programs are mentioned in the book, and the algorithm is improved to varying degrees in the book for different situations.
When he completes the reward mission and unlocks the branch technology of artificial intelligence LV0, these valuable experiences will definitely come in handy.

Even if you give up an annual salary of 500,000 yuan, what else can you not do
Make an APP for online ticket booking
After becoming familiar with the basic operations of the Linux system, Lu Zhou opened the python software, opened the book, and sat in front of the computer in a daze.
"Use crawler technology to crawl the 12306 website's station, train number, and remaining ticket data information... This seems to be possible."
But it's just a big deal. For Lu Xueba, who has already read the entire book, it's not a big problem. The crawler itself is not too technically difficult. The entire program can be completed in less than 30 lines of code, and it runs perfectly without bugs.
Although there are many third-party ticket booking APPs on the Internet, there is really no official ticket booking APP. If he could make something unique and sell it to interested operators, he might be able to earn some living expenses.
Therefore, many "stingy" websites will be equipped with anti-crawler programs. The more technical ones will either prevent you from crawling anything, or the crawled ones will be garbled. The less technical ones can also be directly locked by monitoring the number of visits. your IP.
It’s just that it may cost a lot of money to purchase and maintain a server. The electricity bills and various maintenance costs for operating the server may also be a big expense...

Gritting his teeth, Lu Zhou decided to overcome these difficulties.
Thinking of this, Lu Zhou looked up at the wall clock.
Even if you fail, it doesn't matter if you just do the lessons and practice your skills.
And he only has less than 10,000 yuan in his card, so it might be difficult for him to even light a small flame.
The computer room was quite deserted, with not a single person in sight.

Looking at the train data piling up in the folder, Lu Zhou rolled his eyes, wondering if he should use it for something
After saving the word document, Lu Zhou rolled up his sleeves enthusiastically and put his hands on the keyboard.

Of course, 12306 is not an ordinary BBS forum after all. It is still quite difficult to use this as a practice target for beginners.

Lu Zhou's own second-hand notebook was really rubbish. He had to pretend to be dead for a while to convert the paper into PDF format. He didn't get online until other people started to play online. There was no need to install dual systems or virtual machines and other cumbersome operations. Thought.

The reason why I chose the computer room of the school is mainly because the programs written in python language are mainly run under the Linux system. Learning python language directly in the Linux environment can be said to kill two birds with one stone.

Of course, the advantages of Linux are also obvious. Its super customizability and security make it more suitable for servers and other fields than Windows systems. And once you are familiar with command line operations, the efficiency will be several times higher than that of Windows system. Therefore, when many companies recruit server front-end and back-end programmers, they will ask whether they can use the Linux system.

"But the ticket will automatically be swiped when you hang up... I haven't seen it before." Thinking about last year's winter vacation, when the tickets were booked late, a few animals in the dormitory sat in front of the computer and pressed F5 for almost half an hour before they swiped out a few tickets. After Zhang Zhang's return ticket, Lu Zhou deeply felt that it was not easy for the working people to return home during the New Year.
Suddenly, Lu Zhou's heart moved.
Thinking of this, Lu Zhou looked up at the wall clock.
However, the 12306 website is obviously not that stingy. Think about it, a monopoly giant that doesn’t even care about user experience, would it care about server resources? As long as you don't mess with my server, who cares about you!
"The interface can be simple, but the information must be accurate and comprehensive. You can refer to mainstream third-party ticket booking APPs for this, but they must not be completely similar. There must be innovations... "
"When it comes to one of the applications of Python is to write web crawlers. If you want to test your learning results, this is the best place to start... But what kind of crawler should you make?"
Copying the URL of the website behind the code, Lu Zhou chose to run it, generated a table from the data, and imported it into the pre-built folder.
As he wrote this, Lu Zhou gently rubbed the keyboard with his index finger. He thought for a long time before continuing to type on the keyboard.
After walking over and turning on the air conditioner, Lu Zhou found a computer and sat down. He entered his student ID and password and logged into the computer skillfully.
Lu Zhou, who was using the Linux system for the first time, felt blind. He followed the tutorial borrowed from the library for a long time before he finally figured out the ropes.
As soon as this impromptu idea emerged, it took root and sprouted in his heart uncontrollably.

"Train ticket query must crawl real-time data, which requires very high performance of the server, and the code must be as concise as possible!"
For example, set a time period and several trains, and the server will automatically refresh the data for the user, and submit the order the moment the remaining tickets appear. It seems that among the several ticket-grabbing software he has seen so far, this function is not available.
