PyCharm is a very popular Python integrated development environment (IDE). It provides rich functions and powerful shortcut keys to facilitate developers to write code more efficiently. One of the important functions is code formatting, which can make our code neatly formatted and more readable.

In this article, I will introduce you to some commonly used shortcut keys for code formatting in PyCharm, and give specific code examples to help you get started easily.

1. Format the entire file: Ctrl Alt L

This shortcut key can format the code in the entire file at once, including indentation, spaces, newlines, etc. . For example, our code is as follows:

def foo():
x=1
if x > 0:
print("x is positive")
else:
print("x is negative")

After using the shortcut key Ctrl Alt L, the code will be formatted as:

def foo():
    x = 1
    if x > 0:
        print("x is positive")
    else:
        print("x is negative")

2. Format the selected code block: Ctrl Alt Shift L

Sometimes, we only need to format the selected part of the code, we can use this shortcut key. For example, we select the following code block:

if x > 0:
    print("x is positive")
else:
    print("x is negative")

After using the shortcut key Ctrl Alt Shift L, the selected code block will be formatted as:

if x > 0:
    print("x is positive")
else:
    print("x is negative")

3. Automatically adjust the indentation of the line :Tab/Shift Tab

When writing code, you often need to adjust the indentation of a line. PyCharm provides two methods: increasing the indentation Tab and reducing the indentation Shift Tab. For example, our code is as follows:

if x > 0:
print("x is positive")

After using the shortcut key Tab, the code will be adjusted to:

if x > 0:
    print("x is positive")

After using the shortcut key Shift Tab, the code will be adjusted to:

if x > 0:
print("x is positive")

4. Automatic alignment: Ctrl Alt I

This shortcut key can automatically align multi-line assignments, function parameters, dictionaries, etc. in the code. For example, our code is as follows:

x = 1
y = 2
z = 3

After using the shortcut key Ctrl Alt I, the code will be aligned as:

x = 1
y = 2
z = 3

5. Quickly comment the code: Ctrl /

This shortcut key can quickly comment or uncomment code. For example, our code is as follows:

x = 1
# y = 2
z = 3

After using the shortcut key Ctrl /, the code will be commented as:

# x = 1
# y = 2
# z = 3

Summary:

Through these shortcut keys provided by PyCharm, We can easily format and adjust the code to make it more beautiful and readable. The above are some commonly used shortcut keys, I hope they can help you write code more efficiently when using PyCharm.

Through actual code examples, we can feel the power of PyCharm more intuitively. However, it should be noted that the formatting of the code is mainly to improve the convenience of reading and maintenance. Personal habits may be different. It is recommended to uniformly agree on formatting specifications during team development.

I hope this article can help you use code formatting in PyCharm, making coding more efficient and comfortable!
