Efficient programming tool: Master the PyCharm multi-line comment shortcut keys

In recent years, with the popularity of the Python programming language, more and more developers have begun to choose to use it PyCharm serves as their integrated development environment (IDE). PyCharm provides many powerful features and tools to help developers write and debug Python code more efficiently. Among them, mastering PyCharm's multi-line comment shortcut keys is a very important skill. This article will introduce this function in detail and provide specific code examples.

1. What is a multi-line comment?

In the process of writing code, we often use comments. Comments are text that explains and explains the code. They will not be executed by the compiler or interpreter, but are just to help developers understand the function and logic of the code. Comments in Python start with the # character, and the following text is considered a comment.

Single-line comments are very simple and clear, but when multiple lines of code need to be commented, using multi-line comments will be more convenient and intuitive. Multi-line comments start with ''' or """ and end with ''' or """. In PyCharm, we can quickly comment multiple lines of code through shortcut keys.

2. PyCharm multi-line comment shortcut key

  1. Method 1: Use the shortcut key Ctrl / (Command /)

In PyCharm, use Ctrl / (Windows) or Command / (Mac) shortcut keys to quickly comment out single lines of code. But for multiple lines of code, we need to use different shortcut keys.

  • Add a blank line above the multiple lines of code that need to be commented.
  • Select the code block that needs to be commented, and use the shortcut key Ctrl / (Windows) or Command / (Mac) to comment.

Sample code:

# 这是一段需要注释的代码
# print("Hello, World!")
# print("Welcome to PyCharm")

Commented code:

"""
这是一段需要注释的代码
print("Hello, World!")
print("Welcome to PyCharm")
"""
  1. Method 2: Use the shortcut key Ctrl Shift / (Command Shift /)

Another shortcut key is Ctrl Shift / (Windows) or Command Shift / (Mac). Use this shortcut key to quickly add/delete multi-line comments.

  • Add a blank line above the multiple lines of code that need to be commented.
  • Select the code block that needs to be commented, and use the shortcut key Ctrl Shift / (Windows) or Command Shift / (Mac) to comment.

Sample code:

# 这是一段需要注释的代码
print("Hello, World!")
print("Welcome to PyCharm")

Commented code:

"""
这是一段需要注释的代码
print("Hello, World!")
print("Welcome to PyCharm")
"""

3. Summary

Mastering PyCharm’s multi-line comment shortcut keys can help Developers write and manage code more efficiently. Whether you're commenting an entire function, class, or piece of code, using multiline comments can make your code clearer and more readable. By using the shortcut key Ctrl / or Ctrl Shift /, we can easily add and delete multi-line comments in PyCharm.

In actual development, multi-line comments not only help to add explanations and explanations to the code, but also provide teammates with better code understanding and maintenance convenience. Therefore, mastering PyCharm's multi-line comment shortcut keys is one of the very useful skills for programmers.

I hope this article will help you understand and master the PyCharm multi-line comment shortcut keys. I hope you can improve efficiency in the programming process and write better Python code!

The methods to debug the shebang problem include: 1. Check the shebang line to make sure it is the first line of the script and there are no prefixed spaces; 2. Verify whether the interpreter path is correct; 3. Call the interpreter directly to run the script to isolate the shebang problem; 4. Use strace or trusts to track the system calls; 5. Check the impact of environment variables on shebang.

How do you create multi-dimensional arrays using NumPy?How do you create multi-dimensional arrays using NumPy?Apr 29, 2025 am 12:27 AM

Create multi-dimensional arrays with NumPy can be achieved through the following steps: 1) Use the numpy.array() function to create an array, such as np.array([[1,2,3],[4,5,6]]) to create a 2D array; 2) Use np.zeros(), np.ones(), np.random.random() and other functions to create an array filled with specific values; 3) Understand the shape and size properties of the array to ensure that the length of the sub-array is consistent and avoid errors; 4) Use the np.reshape() function to change the shape of the array; 5) Pay attention to memory usage to ensure that the code is clear and efficient.
