The first quarter of each year is the climax of Python's part-time orders. Recently, the demand for reptiles and data classification services in various industries has increased exponentially. Friends in the circle are not idle, taking advantage of the peak season to make a lot of money.
Therefore, more and more friends have recently consulted on technical realization and part-time orders in the background of the official account.
In the past ten days, I have received more than 600 messages about part-time jobs. I found that some problems occur very frequently. After summarizing everyone's confusion, they can be roughly divided into three situations:
1.0 Basics Want to do part-time Python work, but don't know how to start learning
2. I haven't taken private work, I can't negotiate the price, I have no experience and worry about stepping on the pit
3. Little practical experience, unfamiliar with mainstream technology, worry about not being able to handle the project
What orders can I take?
The first time I received an order was introduced by a friend. At that time, I was just learning Python, crawling data for a company, and earning more than 1,000. Since then, I have gradually become proficient, and often receive some data processing orders during the holidays. In many cases, the income from part-time jobs is 2~3**** times that of the main business .
Most of the part-time orders with a large amount of Python and money are reptiles. It mainly crawls the data of websites, small programs or APPs, analyzes and processes the data, or directly provides crawler programs and technical support to customers. **Which technologies are required for ordering? **Crawler, as the ace technology of Python, is a necessary magic skill for part-time orders. The program principle is very simple, and it is easy to learn.
Ordinary web crawler usually has only four steps: target information website, page crawling, page analysis, and data storage. After understanding the principles and steps, it is easy to crawl the data of ordinary websites.
Of course, this does not mean that this is enough. The real valuable resources are often in large sites with perfect anti-crawling measures. At this time, it is necessary to use the key technology of Python crawler- website anti-crawler strategy and its countermeasures . If you can't handle the anti-crawling measures set by the website, you will not be able to crawl valuable resources, and you will not be able to receive high-value orders. Common anti-reptile measures:
-
The target detects that the crawler has blocked the IP
-
The target returned encrypted data
-
Target returned dirty data, unrecognizable
-
Target website must be logged in to access
-
Javascript dynamic rendering, crawler can not read
-
The target website has a verification code and cannot be accessed
-
Ajax asynchronous transmission, crawler grabs empty information
-
Image camouflage and obfuscation + CSS offset + SVG mapping
No foundation, no experience, how to make money by taking orders?
Going back to the three major problems listed at the beginning, for friends who want to use Python to open up a side business to make money, but are not familiar with crawler and anti-crawler technology, have no way of receiving orders, and lack part-time experience.
I suggest you start learning Python now, many friends will worry about the following issues:
- Will I learn?
- Is Python difficult to learn?
- Is it really suitable for me?
- How long will it take?
- What if no one takes it?
- Where to start learning?
Here I would like to say that instead of considering whether there are some or not, it is better to get started directly and learn it. If you can't learn it yourself, you will know these problems only if you learn it yourself?
blogger's message
That's how I came here in the first place. I've learned it first, and then I'll solve it when I encounter a problem. It's better than just imagining it here. One step at a time, steadily and steadily. I don't believe in learning. If you are ready to learn Python or are learning , you should be able to use the following:
-
① Python learning roadmap in all directions , clear what to learn in each direction
-
② More than 100 Python course videos , covering essential basics, crawler and data analysis
-
③ More than 100 Python practical cases , learning is no longer just theory
-
④ Huawei produces an exclusive Python comic tutorial , which can also be learned on mobile phones
-
⑤ The real Python interview questions of Internet companies over the years are very convenient to review
The full set of Python learning materials mentioned above have been uploaded to CSDN. If you need it, you can scan the CSDN official certification QR code below on WeChat to get it for free [ guaranteed 100% free ]
1. Learning routes in all directions of Python
All directions of Python are to organize the technical points commonly used in Python to form a summary of knowledge points in various fields. Its usefulness is that you can find corresponding learning resources according to the above knowledge points to ensure that you can learn more comprehensively.
2. Python course video
When we watch videos to learn, we can’t move our eyes and brains without hands. The more scientific way of learning is to use them after understanding. At this time, the hands-on project is very suitable.
3. Python practical case
Optical theory is useless. You have to learn to follow along, and you have to do practical exercises before you can apply what you have learned to practice. At this time, you can learn from actual combat cases.
4. Python comic tutorial
Use easy-to-understand comics to teach you how to learn Python, making it easier for you to remember and not boring.
Five, Internet company interview questions
We must learn Python in order to find a high-paying job. The following interview questions are the latest interview materials from first-tier Internet companies such as Ali, Tencent, and Byte, and some Ali bosses have given authoritative answers. After finishing this set The interview materials believe that everyone can find a satisfactory job.
