Adults have only one main job, but they have to pay a price. I was persuaded to step back by personnel, and I cried all night

2022 The second quarter of the year , It is the fiercest layoff on the Internet .

The main reason is that the era policy and demographic dividend of the Internet have come to an end , Blessing of the epidemic . Everyone can't bear it at last .

Crazy layoffs on the Internet , future 5 year , What do migrant workers rely on to resist risks

The rise of big data and artificial intelligence . Nearly period of time , The demand for reptile and digital classification services in various industries has increased exponentially . Many people who have lost their jobs in their main businesses are beginning to realize that their occupational risks are increasing .

It may also be due to the realization of background consulting technology of word-of-mouth publicity in the past 、 There are more and more friends who take orders part-time .

In the last ten days, I have received more than 600 messages about part-time jobs , I find that some problems occur very frequently , After summarizing everyone's confusion , In general, it can be divided into three situations ：

1、0 I want to do Python Part-time job , I don't know how to start learning

2、 No private work , No price negotiation , No experience, worry about stepping on the pit

3、 Little practical experience , Not familiar with mainstream technology , Worried about the project

What orders can I take ？

The first order was introduced by a friend , Just learning at that time Python, Climb data for a company , Made more than a thousand . Since then, I've become proficient , Often receive some data processing orders during holidays , Most of the time, part-time income is the income of the main business 2~3 times .

Python A part-time job with a lot of money , Mostly reptilian . Mainly crawling websites 、 A small program or APP The data of , Analyze and process the data , Or provide crawler programs and technical support directly to customers . What technology does it take to receive an order ？ Reptiles , As Python Ace Technology , It is a necessary magic skill for taking orders part-time . The program principle is very simple , It's easy to learn .

Ordinary web crawlers usually have only four steps ： Target information website 、 Page grabbing 、 Page analysis 、 data storage . After understanding the principles and steps , It's easy to crawl data from ordinary websites .

Of course , That doesn't mean that's enough , Truly valuable resources , Often in large sites with perfect anti crawler measures . At this time , It needs to be used Python The key technology of reptiles —— Website anti crawler strategy and its countermeasures . I'm not sure about the anti crawler measures set up by the website , You can't climb to valuable resources , Even less high-value orders . Common anti reptile measures ：

• The target detected that it was blocked by a reptile IP
• The target returned encrypted data
• The target returned dirty data , Unrecognizable
• The target website must be logged in to access
• Javascript Dynamic rendering , The crawler cannot read
• The target website has a verification code and cannot be accessed
• ajax Asynchronous transmission , Crawler grabs empty information
• Picture camouflage and confusion +CSS The offset +SVG mapping

No basis , He has no experience , How to take orders and make money ？

Go back to the three major issues listed at the beginning , For want to use Python Open up a sideline to make money , But not familiar with reptile and anti reptile Technology , There is no way to receive orders , Friends who also lack part-time experience .

I suggest you start studying now Python, Many friends will worry about these problems ：

• Can I learn ？
• Python Is it difficult to learn ？
• Is it really suitable for me ？
• How long will it take ？
• What if no one brings it ？
• Where to start learning ？
  Here I want to say , Instead of thinking about these, there are some things , Why don't you just get started , Learned again , I can't learn these problems , Only after learning, can I know ？

remarks

That's how I came here , Let's learn first , When you encounter a problem, you are solving it , It's better than daydreaming here . One step at a time , Make steady progress in a down-to-earth manner . I don't believe in learning . If you are ready to learn Python Or learning , You should be able to use the following ：

① Python Learning roadmap in all directions , Know what to learn in all directions

② 100 Multisection Python Course video , Covering the essential basics 、 Reptiles and data analysis

③ 100 Multiple Python Practical cases , Learning is no longer just theory

④ Huawei produces exclusive Python Comic book tutorial , Mobile phones can also learn

⑤ Internet companies over the years Python The real question of the interview , It's very convenient to review
