PyCharm's multi-line comment quick operation: an essential tool to improve development efficiency

PyCharm multi-line comment shortcut keys: a time-saving and efficient development tool

In the daily Python development process, we often need to add comments to explain the functions and functions of the code intention. For longer code blocks or multi-line comments, manually adding comments can be a time-consuming and tedious task. However, PyCharm, as a powerful integrated development environment, provides some shortcut keys in this regard, which can make the process of adding multi-line comments very simple and efficient. This article will introduce the multi-line comment shortcut keys in PyCharm and provide some specific code examples.

1. Comment single line shortcut key

In PyCharm, we can use the Ctrl / shortcut key to comment a single line of code. For example, in the code below, we want to comment out the second line:

x = 10
# y = 20
z = x + y

We just need to put the cursor anywhere on the second line and press Ctrl /, PyCharm The comment symbol # will be automatically added, so that the second line of code is commented:

x = 10
# y = 20
z = x + y

2. Comment multi-line shortcut key

For For multi-line comments, PyCharm provides more convenient shortcut keys to comment multiple lines of code at once. We can use the Ctrl Shift / shortcut key to achieve this. For example, in the following code, we want to comment out the second to fourth lines:

x = 10
y = 20
z = x + y
result = x * z

We only need to select the second to fourth lines of code, and then press Ctrl Shift / , PyCharm will automatically add the comment symbol #, so that the selected code is commented:

x = 10
# y = 20
# z = x + y
# result = x * z

3. Shortcut key to uncomment multiple lines

When we want to cancel multi-line comments, PyCharm also provides shortcut keys. We can use the Ctrl Shift shortcut key to achieve this. For example, in the following commented code, we want to uncomment:

x = 10
# y = 20
# z = x + y
# result = x * z

We only need to select the code in the commented part, and then press Ctrl Shift , and PyCharm will automatically Cancel comments:

x = 10
y = 20
z = x + y
result = x * z

Through the above simple shortcut key operations, we can quickly add and cancel multi-line comments, which greatly improves development efficiency.

Summary:

PyCharm's multi-line comment shortcut key is a very practical function in our daily development, which can help us quickly add and cancel multi-line comments. The existence of this function makes it easier and faster for us to interpret and share code. It is recommended that everyone be familiar with and make reasonable use of these shortcut keys to improve development efficiency.
