Multi-line comment shortcut keys to speed up code editing in PyCharm

PyCharm multi-line comment shortcut key tips to improve code editing speed

In daily development work, code comments are a very important part. It not only helps us record the function and usage of the code, but also makes it easier for other developers to understand our code. However, manually adding comments for each line is a time-consuming task, especially when we need to comment a long piece of code. Fortunately, PyCharm, the Python integrated development environment (IDE) developed by JetBrains, provides shortcut keys for multi-line comments, which can greatly improve our code editing speed. This article will share some shortcut keys for multi-line comments in PyCharm and provide specific code examples.

1. Add multi-line comments

In PyCharm, we can use the shortcut key Ctrl / (Windows/Linux) or Cmd / (Mac) to add multi-line comments. Here is an example:

def add_numbers(a, b):
    """
    This function adds two numbers together.
    :param a: The first number.
    :param b: The second number.
    :return: The sum of the two numbers.
    """
    return a + b

In the above example, we used the shortcut key Ctrl / to comment out three lines of code at the same time. PyCharm will automatically prepend each line with #.

2. Cancel multi-line comments

If we want to cancel multi-line comments, we can select part of the commented code and then use the same shortcut key Ctrl / (Windows/Linux) or Cmd/(Mac) to uncomment. The following is an example of canceling multi-line comments:

# def add_numbers(a, b):
#     """
#     This function adds two numbers together.
#     :param a: The first number.
#     :param b: The second number.
#     :return: The sum of the two numbers.
#     """
#     return a + b

In the above example, we selected the three lines of code that were commented, and then used the shortcut key Ctrl / to cancel the comment. PyCharm will automatically remove # from each line.

3. Add comments line by line

In addition to adding multi-line comments, we can also add comments line by line. In PyCharm, we can use the shortcut key Ctrl Alt / (Windows/Linux) or Cmd / (Mac) to add comments line by line. Here is an example:

def add_numbers(a, b):
    # This function adds two numbers together.
    return a + b

In the above example, we used the shortcut key Ctrl Alt / to comment out the first line of the function at the same time. PyCharm will automatically add # in front of the commented line.

4. Uncomment by line

If we want to uncomment by line, we can select the commented line and then use the same shortcut key Ctrl Alt / (Windows/Linux ) or Cmd/(Mac) to uncomment. The following is an example of uncommenting by line:

def add_numbers(a, b):
    This function adds two numbers together.
    return a + b

In the above example, we selected the commented line and then used the shortcut key Ctrl Alt / to uncomment. PyCharm will automatically delete the preceding #.

Summary:

By using PyCharm shortcut keys, we can easily and quickly add and cancel multi-line comments, thereby improving the speed of code editing. Whether adding multi-line comments for the entire paragraph, or adding and uncommenting by line, PyCharm provides corresponding shortcut keys, allowing us to comment on the code more efficiently. I hope the above tips can help everyone improve coding efficiency.
