PyCharm skills: easily master the operation skills of multi-line comments

As a powerful Python integrated development environment, PyCharm provides many convenient operation skills to help Developers improve work efficiency. Among them, the operation of multi-line comments is also one of the functions frequently used in the development process. In this article, we will introduce how to easily master the operation skills of multi-line comments in PyCharm, and provide specific code examples.

1. Insert multi-line comments in PyCharm

In PyCharm, inserting multi-line comments can be achieved through simple shortcut key operations. Select the appropriate position above or below the code block that needs to be commented, and press the shortcut key Ctrl / (Windows) or Command / (Mac) to insert multi-line comments. For example, we have the following Python code:

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

If we want to make a multi-line comment on this function, just place the cursor above or below the function definition line and press the shortcut key Ctrl / (Windows) or Command / (Mac), PyCharm will automatically insert the multi-line comment symbol "#":

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

This way, multi-line comments can be quickly inserted to facilitate developers to comment.

2. Cancel multi-line comments in PyCharm

Cancel multi-line comments in PyCharm can also be achieved through shortcut key operations. Select the code block that needs to be uncommented, and then press the shortcut key Ctrl / (Windows) or Command / (Mac) to uncomment multiple lines. For example, we have the following multi-line commented code:

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

If we want to cancel the multi-line comment on this function, just select the code block containing the multi-line comment and press the shortcut key Ctrl / (Windows) Or Command / (Mac), PyCharm will automatically cancel multi-line comments:

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

This way, multi-line comments can be quickly canceled to facilitate developers to debug the code.

3. Other techniques for multi-line comments in PyCharm

In addition to the basic inserting and canceling multi-line comment operations, PyCharm also provides some other useful multi-line comment techniques to help developers Use annotation features more efficiently. For example, you can use the shortcut Alt Shift A (Windows) or Option Shift A (Mac) to insert a block comment when multiple lines of code are selected. Alternatively, you can insert multi-line string comments by adding three double quotes above or below the code block.

For example, we can insert multi-line string comments like this:

"""
This is a 
multi-line
string comment
"""

Through the above techniques, developers can use the multi-line comment function in PyCharm more flexibly to improve the readability of the code style sex.

Summary:

Through the introduction of this article, we have learned the operating techniques of inserting and canceling multi-line comments in PyCharm, and learned some other useful multi-line comment techniques. Mastering these skills can help developers use PyCharm for development work more efficiently and improve code quality and maintainability. I hope this article will be helpful to everyone when using PyCharm and make development work easier and more enjoyable!
