Detailed explanation of how to use PyCharm code formatting

PyCharm is a very powerful Python integrated development environment (IDE), which provides many functions in code editing and debugging. Lots of convenient features. Among them, code formatting is an important function of PyCharm, which can help developers maintain a unified code style and good readability. This article will introduce in detail how to use PyCharm code formatting and provide specific code examples.

1. Use shortcut keys for code formatting

PyCharm provides many shortcut keys to facilitate developers to format code. Press Ctrl Alt L (Windows) or Cmd Option L (Mac) to format selected code or the entire file. In addition, you can also format the code through "Code" -> "Reformat Code" in the menu bar.

For example, the following is an unformatted Python code:

def add(x,y):return x+y
print(add(3,5))

After formatting using the shortcut keys, the code will be automatically adjusted to:

def add(x, y):
    return x + y

print(add(3, 5))

2. Self-formatting Define code formatting rules

PyCharm allows developers to customize code formatting rules according to their own needs. You can set it up by following the steps:

1. Open "Preferences" (Windows) or "PyCharm" -> "Preferences" (Mac);
2. In the navigation bar on the left Select "Editor" -> "Code Style";
3. In the "Python" tab on the right, you can set formatting rules for different code elements. For example, you can set the indentation to four spaces, force function and class names to use camelCase, etc.

3. Automatic code correction

In addition to formatting code, PyCharm can also automatically correct some common code errors. For example, when unused variables or imported modules appear in the code, PyCharm will display a small yellow light bulb icon on the right side of the editor. Clicking the icon will pop up a menu where you can choose to delete the unused variables or imported modules. .

4. Code batch formatting

PyCharm can also batch format all codes in the entire project or folder. You can perform batch formatting through the following steps:

1. Select the files or folders to be formatted in the project view;
2. Right-click and select "Reformat Code";
3. Select the "Recursive" option and click the "Run" button.

Summary:

PyCharm code formatting is an important tool to improve code quality and readability. Developers can use shortcut keys, custom rules, automatic correction and batch formatting and other functions to flexibly format code. Proper use of code formatting functions can improve development efficiency and code quality.
