If you ask such a question, it means that you have plans to learn Python. Before learning, you must first understand what Python is? What can I do after I finish my studies?
If you want to learn python systematically, you can get the learning tutorial materials below for free. The materials include a learning roadmap, a full set of basic learning materials and video tutorials. The content is clear, detailed and easy to understand. It is very suitable for beginners to learn. Students who need to scan the QR code below --> add csdn official certification to get it for free
Python is an interpreted, object-oriented high-level programming language.
Interpretation means that we write code in Python, and the written code will be submitted to the interpreter, which will translate the code line by line, and translate the code into machine code that the machine can recognize. Every line of translation is submitted to the machine. Execute one line until all codes are translated.
Object-oriented is like building a house. You let Xiaohong buy cement and screws, let Xiaolan draw drawings, and let Xiaolu build a house. Then this way of letting professional people help you build a house is called object-oriented.
In addition, it also has many features that other programming languages do not have, making Python easy to learn. This is also the main reason why many beginners choose to enter the programming world as their preferred language.
Its application is also very extensive, as follows:
System programming: Provide API (application programming interface), which can facilitate system maintenance and management. It is one of the symbolic languages under Linux and is an ideal programming tool for many system administrators.
Graphics processing: Supported by graphics libraries such as PIL and Tkinter, it is convenient for graphics processing.
Mathematical processing: NumPy extensions provide extensive interfaces to many standard math libraries.
Text processing: The re module provided by Python can support regular expressions, and also provides SGML and XML analysis modules. Many programmers use Python to develop XML programs.
[Database programming]: Programmers can communicate with databases such as Microsoft SQL Server, Oracle, Sybase, DB2, MySQL, and SQLite through modules that follow the Python DB-API (Database Application Programming Interface) specification. Python comes with a Gadfly module that provides a complete SQL environment.
[Network programming]: Provide rich modules to support sockets programming, which can facilitate and quickly develop distributed applications. Many large-scale software development projects such as Zope, Mnet and BitTorrent. Google are using it extensively.
Web programming: application development language, supports the latest XML technology.
Multimedia application: Python's PyOpenGL module encapsulates the "OpenGL application programming interface", which can perform two-dimensional and three-dimensional image processing. The PyGame module can be used to write game software.
Pymo engine: The full name of PYMO is Python memories off, which is an AVG game engine running on Symbian S60V3, Symbian3, S60V5, Symbian3, and Android systems. Because it is developed based on the Python2.0 platform and is suitable for creating AVG games in the style of [Autumn Memories] memories off), it is named PYMO.
Hacker programming: Python has a hack library, which has built-in functions you are familiar with or unfamiliar with, but lacks a sense of accomplishment.
There are many places where Python can be used, whether it is from entry-level beginners to professional-level masters, data mining, scientific computing, image processing, artificial intelligence, Python can be competent. Perhaps because of this universal property, many friends are now learning Python.
Everything is difficult at the beginning, so give a good start to friends who want to learn Python. When you first enter the programming industry, you don’t know whether you can really learn it or worry that you can’t learn it. So before learning, we must have a clear learning goal and a detailed learning route . , so as not to study blindly and avoid detours.
Here I happen to have a set of Python learning materials, which include learning framework routes and video tutorials, which are indeed very suitable for beginners, because I also learned from this set of materials. During this period of time, I reorganized and updated them, and now share them with You ↓↓↓
For friends who plan to work or transfer to the IT industry after completing their studies, the employment prospects of Python are what they value. Due to its wide range of application fields, the employment direction is also very broad! You can choose operation and maintenance, data analysis, crawler engineer, web full-stack engineer, or choose artificial intelligence, which is very popular at present.
Take one of my former company colleagues as an example. Some time ago, he switched to a Python engineer and jumped from 5K+ to 12K+, almost doubled. This should be something that many people dare not dream of, and he told me some The time salary can still be increased, if it doesn't work, just change jobs, and it can directly increase to more than 15K!
Who would not be tempted to hear this, not to mention that I am still a person who has learned Python, but due to some reasons, I have no plans to engage in this industry yet, but I also earn a lot of part-time jobs by taking orders with Python, which will be discussed later.
Then talk about the employment direction, let's have a general understanding:
Python crawler engineer
[Web crawler] is the core tool for data acquisition in the big data industry. Without it automatically, day and night, and highly intelligently crawling free data on the Internet, there may be three-quarters fewer companies related to big data.
There are many programming languages that can write web crawlers, but Python is definitely one of the mainstream, and its Scrapy crawler framework is widely used. I feel that Python is naturally born for crawlers. My first project is to crawl Taobao clothing pictures. It is simple, fast and very fulfilling.
Operation and maintenance development engineer
With the advancement of technology and the rapid growth of business requirements, an operation and maintenance personnel usually has to manage hundreds or thousands of servers, and the operation and maintenance work has become repetitive and complicated. Automating the operation and maintenance work can release the operation and maintenance personnel from the management time of the server, making the operation and maintenance work simple, fast and accurate. In other words, O&M automation is a set of strategies that transform the static equipment structure into a dynamic and elastic response based on IT service requirements. The main purpose is to achieve the quality of IT O&M and reduce costs.
Key issues in automated operation and maintenance: automation, easy implementation, cross-platform, lightweight, exactly these points are the advantages of Python; characteristics suitable for automated operation and maintenance programming languages: rich third-party libraries, low learning costs, cross-platform, lightweight Quantity, and Python has such an advantage.
All in all, Python is a programming language very suitable for automated operation and maintenance.
Data Analyst
On the basis of a large amount of data, combined with scientific computing, machine learning and other technologies, data cleaning, deduplication, normalization and targeted analysis are the cornerstone of the big data industry. Python is one of the mainstream languages for data analysis.
Due to the rise of big data, the demand for data analysis talents is also rising. Because data analysis is used in almost all industries and companies, there are a lot of recruitment positions for data analysis. My goal is to switch to a data analyst, so I will say a few more words here. After learning the crawler, I will have a data source. Use These data and the corresponding crawler libraries and Excel tables can be used for simple data analysis, which is a more advanced position than crawlers.
Web[full stack engineer]
There are too many Python-based web development frameworks, such as the familiar Django, Tornado, and Flask. Among them, the Python+Django architecture has a wide range of applications, very fast development speed, and low learning threshold, which can help you quickly build available web services.
It is recommended that you switch to this direction. First, there are many jobs, and it is relatively easy to find a job; second, the learning cycle is short. You only need to thoroughly understand the basics of Python, the Django framework and the [flask framework], and add some html knowledge, and then You can submit your resume after doing some projects.
In fact, there are still many directions, so I won’t introduce them one by one. Friends who are interested can go to my homepage to have a look, where there are detailed explanations. From the above positions, we can also see how broad the employment prospects of Python are.
But many people also have the idea of doing some part-time jobs to make money after learning Python. Now I can take tens of thousands of side jobs every month, so it is relatively impressive. It is also a very good choice to use Python to do part-time jobs (only on behalf of personal income).

Nowadays, earning money online is relatively easy and popular, and you can receive orders without leaving your home. Various Internet platforms and social platforms will have people post programming tasks and pay corresponding rewards. Generally, they are simple and small tasks, such as Python. If you use your knowledge a little bit, you can earn money. When I was not familiar with it before, I was only in some order-taking groups, and there were a lot of them in a search on QQ. There were many people there who sent needs, so I just looked at it and did it myself.
In addition, there are many open source systems on the Internet, and some open source systems require different plug-ins to meet various customized needs of customers. At this time, you can use Python to develop some commonly used plug-ins and publish them on the Internet. When someone needs to use your plug-ins, You can charge to earn benefits!
Also, the game industry is actually very profitable now, and you can also use game scripts to make money. Maybe your Python knowledge is not enough to develop a whole set of games, but you can do a small part of a certain game, which is suitable for some small game companies or outsourcing companies. You don’t have to participate in the entire development team, just be a peripheral Program supporters can make money if the things they make can be adopted by others.
In terms of self-media operations, Python has ushered in a boom, and more and more people know the importance of this small tool, and then more people participate in learning and research. At this time, you can use the Python you have mastered Knowledge Write some popular science articles, learning experience, or record some professional videos for learners to read to get traffic, so that you can make money through traffic.
If you also want to make money through Python orders, you must first learn Python well. In fact, don’t look at it as a programming thing. Don’t think that you have never been exposed to it and worry that you can’t learn it, but think about who is born with it? Who doesn't master the skills after learning the day after tomorrow? So first of all, you must have confidence in yourself. It just so happens that there is a set of learning materials for getting started with Python, including learning framework routes and video tutorials, to help beginners with zero foundation quickly master the basics of Python.
The following are some of my experience in receiving orders for so long, and I can learn from them if necessary.
Simple formula: project working hours * daily salary + urgency + quotation
This will help you to quote as much price as possible when quoting. However, when the customer is negotiating the price, your own side is also justified, which is beneficial to your own side to have a higher return.
**Note:**Remember to leave a small bug to prevent the final payment from being not paid, because I have experienced it, and I would like to remind everyone here that some customers are really savage. I don’t know them very well. Balance payment.
There are some other order considerations:
- To prevent being cheated, do not lock the program when the program is finished and the money is not settled. Add a few lines of code at the front of the program, requiring a key to open the program. If the verification is correct, the program will open and close without the key
- Before doing the work, find out whether the remuneration mentioned by the client is pre-tax or after-tax
- Don’t set the time with the customer. If the program is changed over and over again, there will be problems, and it will take time to fix it.
- Before doing the work, communicate with the customer well, and the construction period must be clear
- Clarify requirements and maintain communication
- Do it in your spare time, don't delay your main business
- Personal bills without third-party guarantees are more risky and should be avoided as much as possible
- There is no requirement document, and those who cannot explain the specific requirements do not accept
- If there is no prepayment, do not do it, and the settlement method is 442
In addition to the channels mentioned above, you can also receive orders through some website platforms, such as Mashi, [Yipin Witkey], Yuanjisong and other platforms to receive orders and get paid. Different tasks require different difficulties, and the obtained The remuneration also varies from high to low, just choose the one that suits you and ensure completion.
