A simple introductory guide to PyCharm code formatting

In the process of writing Python code, good code format is the key to ensuring code readability and maintainability . As a powerful integrated development environment, PyCharm provides convenient code formatting tools that can help developers automatically adjust the format of the code to make it comply with unified coding standards. This article will briefly introduce the basic operations and common functions of PyCharm code formatting, and demonstrate it with specific code examples.

First, open PyCharm and create a new Python project. Create a Python file in the project, for example named "format_example.py". Next, we will demonstrate how to use PyCharm for code formatting.

1. Use shortcut keys to format code

PyCharm provides shortcut keys to help quickly format code. During the process of editing code, you can use the shortcut key combination Ctrl Alt L (Windows/Linux) or Command Option L (Mac) to format the currently edited code.

# 示例代码
def example_func():
message = "hello"  # 未对齐的代码
return message

After pressing the shortcut key combination, PyCharm will automatically adjust the indentation and alignment of the code to make it more clear and readable.

# 格式化后的代码
def example_func():
    message = "hello"  # 对齐后的代码
    return message

2. Configure code formatting rules

PyCharm also allows users to customize code formatting rules to meet the coding style conventions within the project team. In PyCharm, you can enter Settings -> Editor -> Code Style to configure code formatting options, such as indentation, spaces, newlines, etc.

3. Automatically apply code formatting

In addition to manually formatting code using shortcut keys, PyCharm can also be set to automatically apply code formatting. Find Editor -> Code Style -> Python in Settings, check the "Enable formatter markers in comments" option, and set custom formatting markers:

# fmt: off
def long_function_name(
    var_one, var_two, var_three, var_four):
    return var_one * var_two - 
           var_three / var_four
# fmt: on

Insert # in the code The code blocks between fmt: off and # fmt: on will not be changed by PyCharm formatting and can retain the original format.

Summary:
Through this simple introductory guide, you can master the basic operations and common functions of PyCharm code formatting, and improve the readability and neatness of the code. Use PyCharm's code formatting tools to make coding more efficient and enjoyable. I hope this article is helpful to you and I wish you happy programming!
