Get it done with one click! PyCharm batch annotation tutorial sharing, specific code examples are required

With the popularity of the Python language and the expansion of application scenarios, more and more developers choose to use PyCharm as the development environment. In the development process, comments are a very important part. It can improve code readability, facilitate team collaboration and later maintenance. However, adding comments manually is often time-consuming and cumbersome. Is there a one-click way to do it? The answer is yes! This article will share how to use PyCharm's function to batch comment code with one click and provide specific code examples.

First, we need to understand the annotation function in PyCharm. In PyCharm, we can use the shortcut key Ctrl / to add or cancel single-line comments, and use Ctrl Shift / to add or cancel multi-line comments. Using these shortcut keys, we can perform annotation operations quickly and easily. Next, we will introduce how to batch comment code.

1. Batch comment multiple lines of code:

Imagine the following scenario, we need to comment multiple lines of code in a function. Adding comments line by line manually is obviously very troublesome. At this time, we can use PyCharm's shortcut keys to achieve one-click batch annotation.

First, select the multiple lines of code that need to be commented, and then press Ctrl Shift /. PyCharm will automatically add a comment symbol in front of each line to comment out the selected multiple lines of code.

2. Batch cancellation of code comments:

If we need to cancel the commented code, we can also use PyCharm's shortcut keys to achieve this. Select multiple lines of code that have been commented and press Ctrl Shift /. PyCharm will automatically cancel the comment symbol before each line of code to achieve the purpose of batch uncommenting.

In addition, in PyCharm settings, we can also customize shortcut keys. Click the "File" menu, select "Settings", and select the "Keymap" option in the pop-up dialog box to set and customize shortcut keys. If you feel that the default shortcut keys are not convenient enough, you can adjust them according to your personal habits to improve operating efficiency.

Next, let us use a specific code example to demonstrate how to use PyCharm to implement one-click batch annotation.

def add(a, b):
    # 这是一个加法函数
    return a + b

def subtract(a, b):
    # 这是一个减法函数
    return a - b

def multiply(a, b):
    # 这是一个乘法函数
    return a * b

def divide(a, b):
    # 这是一个除法函数
    return a / b

The above is an example of a simple mathematical operation function. Now, we need to batch annotate each function.

First, select all lines of code (click the first line with the mouse, then hold down the Shift key, and click the last line), press Ctrl Shift /, PyCharm will add comment symbols at the beginning of each function. The code after completing the comments is as follows:

# def add(a, b):
#     # 这是一个加法函数
#     return a + b
#
# def subtract(a, b):
#     # 这是一个减法函数
#     return a - b
#
# def multiply(a, b):
#     # 这是一个乘法函数
#     return a * b
#
# def divide(a, b):
#     # 这是一个除法函数
#     return a / b

So simple and fast! We only need a shortcut key to easily implement batch annotation operations.

In actual development, comments are a very important part. It not only improves the readability of the code, facilitates code maintenance and team collaboration, but also helps other developers better understand the code we write. Using PyCharm's batch annotation function, we can perform annotation operations more efficiently and greatly improve work efficiency.

Through the introduction of this article, we have learned about PyCharm's batch comment function and provided specific code examples, hoping to help developers who are using PyCharm. I wish you all a happy use and writing efficient Python code!
