Advanced tips and tricks for PyCharm code formatting

Introduction:
PyCharm is a popular Python integrated development environment (IDE) that provides It provides a wealth of functions and tools to help developers improve development efficiency. One of them is code formatting. Code formatting can make your code cleaner and easier to read, reducing errors and debugging time. This article will introduce some advanced tips and techniques for code formatting in PyCharm and provide specific code examples.

Tip 1: Use automatic formatting shortcut keys
PyCharm provides a powerful automatic formatting function that can help us quickly format the code. In the default settings, the shortcut key Ctrl Alt L (Windows/Linux) or Cmd Option L (Mac) can format all code in the current file according to the PEP8 specification. In addition, you can also select part of the code for formatting. Just select the code and press the above shortcut keys.

The following is a sample code:

def calculate_area(length, width):
    return length * width


def calculate_volume(length, width, height):
    return length * width * height


def display_result(area, volume):
    print("The area is:", area)
    print("The volume is:", volume)


length = 5
width = 10
height = 3

area = calculate_area(length, width)
volume = calculate_volume(length, width, height)
display_result(area, volume)

Tip 2: Customized code style
PyCharm allows us to customize the code style according to personal preferences. First, click File -> Settings -> Editor -> Code Style to open the code style settings window. Then, select the appropriate language, such as Python, and various code styles can be customized in the right panel.

The following is a sample code style setting interface:

    [x] Class
        [x] Keep line break before first field
    
    [x] Blank lines
        [x] Keep maximum blank lines
        [x] Keep blank lines before "def"
        
    [x] Spaces
        [x] Method parentheses
            (x) Space within    
            ( ) Space before
            ( ) Space after

Tip 3: Use code templates
PyCharm provides a code template function that can help us write code faster. Code templates are predefined code snippets that can be adapted and extended as needed. Click File -> Settings -> Editor -> Live Templates to open the code template settings window. You can see many defined code templates, such as if, for , while, etc. Additionally, you can create your own code templates.

The following is a sample code template:

if __name__ == "__main__":
    $END$

Tip 4: Use the automatic import function
PyCharm's automatic import function can help us automatically add the required import statements. When we use an unimported module or function, PyCharm will automatically prompt and provide import options. We only need to select the required import statement, and PyCharm will automatically add the selected import statement to the head of the file.

The following is a sample code:

import datetime

current_time = datetime.datetime.now()
print(current_time)
