How to use PyCharm for code formatting

PyCharm is a powerful Python integrated development environment (IDE). Its code beautification tool can help developers standardize code style, optimize code structure, and improve code readability. This article will introduce how to use the PyCharm code beautification tool, and explain it in detail with specific code examples.

1. Install the code beautification tool

First, make sure PyCharm is installed and open the Python project to be code beautified. Next, we need to install a code beautification tool called "black". In PyCharm, you can install "black" through the following steps:

1. Open PyCharm and select"File" -> "Settings" in the top menu bar.
2. Select"Project: [your project name]" -> "Python Interpreter" in the Settings window.
3. Click the " " symbol in the upper right corner, search for "black" and install it.

2. Use the code beautification tool

After the installation is completed, we can beautify the code in the following two ways:

1. Use shortcut keys to quickly beautify the code: In PyCharm, you can use shortcut keys to quickly beautify the code. By default, the shortcut key for "black" is Ctrl Alt L. Select the code you want to beautify and press the shortcut key to beautify the code.
2. Beautify the code through the right-click menu: You can also beautify the code through the right-click menu. In the code area that needs to be beautified, right-click the mouse and select "Reformat with Black" to complete the code beautification.

3. Code Example

Let us demonstrate the use of code beautification tools through a specific code example. Suppose we have the following Python code:

def add(a,b):
return a+b

Next, we use the code beautification tool "black" provided by PyCharm to beautify the above code. Select the code area and press Ctrl Alt L or right-click "Reformat with Black". The beautified code is as follows:

def add(a, b):
    return a + b

Using the "black" code beautification tool, we successfully adjusted the original code structure and added indentation to make the code clearer and easier to read.

4. Summary

In this article, we introduce the installation and use of the PyCharm code beautification tool, and demonstrate it with specific code examples. By using code beautification tools, we can effectively standardize code style, improve code quality, and thereby improve development efficiency. I hope this article will be helpful to you when using PyCharm for code beautification. ​​​​​
