PyCharm multi-line comment shortcut key skills: a simple and efficient learning method

Easy-to-learn PyCharm multi-line comment shortcut key skills

PyCharm is a powerful Python integrated development environment that provides many shortcut keys and Tips, one of which is shortcut keys for multi-line comments. In the process of writing code, we often need to add comments to explain the role and function of the code, and PyCharm's multi-line comment shortcut keys can help us quickly add or cancel comments, improving the readability and maintainability of the code. This article will introduce the shortcut key techniques for multi-line comments in PyCharm, and provide specific code examples to help readers better understand and apply them.

In PyCharm, we can use the shortcut key Ctrl / to add or cancel single-line comments. But in the scenario of multi-line comments, the single-line comment shortcut key is obviously not enough. PyCharm provides a more powerful shortcut key Ctrl Shift /, which can add or cancel multiple line comments at the same time. The following are the specific steps:

1. Select the multiple lines of code that need to be commented.
2. Use the shortcut key Ctrl Shift / to add or cancel multi-line comments.

Below, we will use sample code to demonstrate the shortcut key skills of multi-line comments:

# 示例代码1：使用多行注释快速添加注释
def add(num1, num2):
    """
    这是一个用于计算两个数相加的函数
    :param num1: 第一个数字
    :param num2: 第二个数字
    :return: 两个数字的和
    """
    return num1 + num2

In the above sample code, we use multi-line comments to annotate functions illustrate. By selecting the code block that needs to be commented and using the Ctrl Shift / shortcut key, PyCharm will automatically add the comment symbol ''' above the selected code, and at the same time add the comment symbol ''' at the end of the code block, so that the selected code is implemented Multi-line comments.

In addition to adding comments through multi-line comment shortcut keys, we can also use the same shortcut keys to cancel multi-line comments. Just select the commented code block again, use Ctrl Shift / shortcut key, PyCharm will automatically delete the comment symbol ''' in the code, thereby canceling multi-line comments.

# 示例代码2：使用多行注释快速取消注释
#def subtract(num1, num2):
#    """
#    这是一个用于计算两个数相减的函数
#    :param num1: 第一个数字
#    :param num2: 第二个数字
#    :return: 两个数字的差
#    """
#    return num1 - num2

In the above example code 2, we used multi-line comments to annotate the function. Select the commented code block again, use Ctrl Shift / shortcut key, PyCharm will automatically delete the comment symbol ''' in the code, thereby uncommenting.

By adding and canceling multi-line comments through shortcut keys, we can more conveniently comment on the code and cancel the comments, which improves the readability and maintainability of the code.

Summary:
This article introduces the shortcut key skills for adding and canceling multi-line comments in PyCharm, and demonstrates its use through specific code examples. Use the shortcut key Ctrl Shift / to effectively add or cancel multi-line comments. When writing code, we can use this technique to improve the readability and maintainability of the code. I hope these tips will provide some help to readers when using PyCharm for Python development.
