13- Double click the PyCharm on the desktop

Give it any name (I named it Learning), then click create. If you encounter the following situation, click ok (if not encountered, just ignore it)14- Add InterpreterSuccessfully as follows:Print successfully: indicating configuration is complete

4. Configure Mirror Sources for Faster Downloads

Insert image description here

I prefer using Tsinghua’s, so I will introduce Tsinghua source here, of course, here are some good mirror sources:

    Tsinghua:
    
    https:/
    /pypi.tuna.tsinghua.edu.cn/simple
    



    Aliyun:
    
    http:/
    /mirrors.aliyun.com/pypi
    /simple/
    



    University of Science and Technology of China
    
    https:/
    /pypi.mirrors.ustc.edu.cn/simple
    

There are three types of mirror source configurations, I suggest you learn each one with me.

4.1) Internal Configuration of PyCharm

Step 1:Step 2:Step 3:Step 4: Copy the Tsinghua mirror source from above, paste, then okokokokTest, if you encounter this problem: pip: cannot recognize “pip” as cmdlet, function, script file, or executable program name. Please check the spelling of the name, and if including the path, ensure the path is correct, then try again.Because I forgot to add pip to the environment variable, so add it, once like this:

Step 5: Exit PyCharm, because adding the environment variable requires restarting the software. We first go to cmd and enter pip, as shown here indicates successful configuration:Step 6: After restarting the software, casually install a module, as follows: (you can see the download module speed is very fast!)

4.2) Manually Add Mirror Sources

Usage:

pip install module_name -i https://pypi.tuna.tsinghua.edu.cn/simple

For example, if I want to download the numpy module, execute the following command:

pip install numpy -i https://pypi.tuna.tsinghua.edu.cn/simple

It will be done in a few seconds:The advantage of this method is that you don’t need to configure it like the other configurations, you just need to add:

-i https://pypi.tuna.tsinghua.edu.cn/simple

4.3) Permanently Configure Mirror Sources

This configuration is one I strongly suggest you add. Method 1: Execute the following command in cmd to create pip.ini:

pip config set global.index-url https://pypi.tuna.tsinghua.edu.cn/simple

Return:

Then we just need to add this path to the system environment variable (How to add environment variables? The same operation as adding the environment variable for pip, just a different path)

Method 2:

If the command you just executed failed, you can create a folder named pip in any location on the C drive, and create a file named pip.ini under it, with the content as follows:

    [
    global]
    

    index-url = 
    https:
    //pypi.tuna.tsinghua.edu.cn/simple
    

Then add it to the environment variable.

5. Install Plugins (e.g., Localization?)

Insert image description here

First of all, I personally do not recommend localization, finally, I will demonstrate the localization plugin. I want to recommend some good plugins. First, enter the following interface:

5.1) First Code Completion Tool

Recommended to use: TabNine, of course, Kite is also good, you can install them both, I am using both. I will demonstrate one:

This pop-up page can be ignored:Testing: Already started to have prompts

5.2) Second Code Completion Tool

(You can also scan the QR code at the bottom) Go to my public account: Python Tutorial Network and send: python to get the Kite software, just install and configure it without thinking. If you really can’t, add me on the left side and I will tell you.

Directly jump to this article of mine, if your effect is the same as mine, then it is successful: Kite Tool

5.3) Localize PyCharm

First of all, I personally do not recommend localization, whether your English is good or bad, you should adapt to this English interface. Of course, if you really need localization, here is the tutorial:

Now it has been fully localized:

5.4) Other Plugins

If you need to download other plugins, you can search for good PyCharm plugins on Baidu, all installed using the above methods.

6. Beautiful Backgrounds

Do you want a desktop like this?

Tutorial link: Setting up Beautiful Desktop Backgrounds

7. Customize Script Header

Do you always create a file and start with the following?Save space, jump to this article: Customize Script Header

8. Ready to Start Coding!

Having this article means you have the most complete book, covering more than the books, and the syntax will be more detailed than the purchased books, everyone should take it slow. With this article, you will have a solid foundation and can self-learn some advanced tutorials. The author has written for several days and is really tired, hope you can support me.

Python, in short, is: easy to understand, powerful, quick to get started, and practical. If you study this article seriously, you will definitely learn the most solid Python basics. Meanwhile, I can provide free tutoring, as the author is a student and does not seek any benefits. If you need tutoring, you can join the group from the left sidebar, of course, it’s just for communication, I won’t have time to teach you all the time, I can only help you solve some problems, more depends on yourself.

9. Introduction to Python

I won’t introduce software installation, just search for Python and PyCharm installation on Bilibili, personally, I recommend using Python and PyCharm together. What is PyCharm? It is a compiler for Python. If we don’t have a compiler, it is very difficult to write code, and PyCharm provides many plugins and a beautiful interface, making your coding fast and comfortable, without headache from writing on Python’s IDE.

Note: Make sure the number of variables matches the number of values, otherwise, you will get an error.

Multiple variables with one value
