VS Code It doesn't include Python Of , So first you have to install a Python.
installed python after , We can start writing with any text editing tool python Code , And then in cmd Run code in .
stay VS Code in , Without installing any plug-ins , It can also run python Code .
Create a new one test.py file , Input print('Hello World!').
Click on see -> terminal （ Shortcut key Ctrl + `） Open the terminal , Input python test.py You can run , With the cmd Run in python The code is the same .
Without installing the plug-in , Click on debugging -> Start debugging （ Shortcut key F5） There's no way to run the code . Will let you choose the environment , And you don't have an environment at all .
stay VS Code The app store （ Shortcut key ：Ctrl + Shift + X） Search inside Python plug-in unit , And install . Here's the picture ：
Press Ctrl + Shift + P（ or F1）, Enter in the open input box Python: Select Interpreter Search for , choice Python Parser .
After choosing the parser , We can go straight to VS Code Running in （ Shortcut key Ctrl + F5） Or debugging （ Shortcut key F5）Python Code. .
Python The most powerful is the external library , stay PyCharm in , Can be in Settings View in 、 Search for 、 install . So in VS Code How to install it in ？
As mentioned above , It can run directly at the terminal .py file , Actually , A terminal is a command prompt （cmd）, So it's OK to directly input the corresponding command at the terminal .
View the list of installed packages ：
pip list Copy code
Install external library ：
pip install xxx Copy code
Be careful ： When the machine is installed with more than one Python When it comes to parsers ,pip It may not be installed in the current parser Directory . I tested this many times and found that , It should be related to the order of environment variables , It will be installed in the directory of the top parser in the environment variable .
VS Code The code completion plug-in in is Visual Studio IntelliCode. Also install through the app store .
Visual Studio IntelliCode It's a set AI Auxiliary function , It can be sensed through context intelligence , The functions of reasoning and execution of code style improve the working efficiency of developers .
IntelliCode Generate recommendations by using machine learning models trained in thousands of common code bases , And it will grow as you write code , To become more accurate . It gives programming advice based on context , Instead of simply recommending by alphabetical order API.
The most important IntelliCode Has supported Python. After the installation , There can be intelligent tips .
PyCharm With code checking tools , and VS Code None of them .
When you build .py file , When you start writing code , The bottom right corner may jump out of this （ The old version will , The new version will not ）：
Pylint It's a Python Code checker . Need to pass through pip install .
Open Settings , Add the following settings ：
"python.linting.enabled": true, "python.linting.pylintEnabled": true, Copy code
And then for code that doesn't meet the specification , There will be a wave line hint .
stay VS Code 1.36.1 edition , Seems not to design
python.linting.enabled": trueIt's fine too .
flake8 By Python An official test aid Python Is the code a standardized tool , Compared with the current high heat Pylint Come on ,Flake8 Flexible inspection rules , Support for integration of additional plug-ins , Extensibility is strong .Flake8 It's the encapsulation of the following three tools ：
Official document address ：pypi.python.org/pypi/flake8…
yapf Is a code format tool .
adopt pip Install well Flake8 and Yapf after , Configure as follows .
"python.linting.enabled": true, "python.linting.pylintEnabled": false, "python.linting.flake8Enabled": true, "python.formatting.provider": "yapf", Copy code
If installed pylint Words , To set it
Enabled = false, Otherwise, you don't have to .
Once installed , We are in the code file （.py） In the right , Choose format document , You can format the code automatically .
Code checking tools are good , But some strict inspections are not in line with our habits , for example flake8 The default maximum number of characters in a line is 79 individual , If the code is too long, the wavy line will be displayed .
79 The character is too short , We can make it longer , Add the following configuration , Set the maximum length to 128 Characters .
"python.linting.flake8Args": ["--max-line-length=128"],
