Pycharm quick comment method: 1. For single-line comments, use the "Ctrl /" shortcut key to comment out the line where the cursor is; 2. For multi-line comments, use the mouse to select the line of code to be commented, and then use " Ctrl /" shortcut key can comment out the selected line of code; 3. Block comment, add three single quotes or double quotes before and after the code block to be commented, and the entire code block can be commented out. In addition, use the "Ctrl Shift /" shortcut key to toggle single-line comments, uncomment, and more.

In PyCharm, you can use shortcut keys to quickly comment or uncomment code. The following are several ways to comment code in PyCharm:
1. Single-line comment:
Use the Ctrl/shortcut key to comment out the line where the cursor is. If you want to cancel a comment, you can also use the same shortcut key.
2. Multi-line comments:
First, use the mouse to select the line of code to be commented, and then use the Ctrl/shortcut key to comment out the selected line of code. Likewise, if you want to cancel a comment, you can use the same shortcut key.
3. Block comments:
Add three single quotes or double quotes before and after the code block to be commented to comment out the entire code block. When uncommenting, just remove the three quotation marks.
In addition to using shortcut keys, you can also use the right-click menu to comment or uncomment. Right-click on the line or code block you want to comment and select the "Comment with Line Comment" or "Comment with Block Comment" option to comment. To uncomment, select the "Uncomment" option.
In addition, PyCharm also supports using shortcut keys and the right mouse button menu to switch between commenting and uncommenting. For example, use the Ctrl Shift/ shortcut to toggle single-line comments and uncomments, and use the Ctrl Shift C and Ctrl Shift X shortcuts to toggle block comments and uncomments.
The above is the detailed content of How to quickly comment in pycharm. For more information, please follow other related articles on the PHP Chinese website!
What are the alternatives to concatenate two lists in Python?May 09, 2025 am 12:16 AMThere are many methods to connect two lists in Python: 1. Use operators, which are simple but inefficient in large lists; 2. Use extend method, which is efficient but will modify the original list; 3. Use the = operator, which is both efficient and readable; 4. Use itertools.chain function, which is memory efficient but requires additional import; 5. Use list parsing, which is elegant but may be too complex. The selection method should be based on the code context and requirements.
Python: Efficient Ways to Merge Two ListsMay 09, 2025 am 12:15 AMThere are many ways to merge Python lists: 1. Use operators, which are simple but not memory efficient for large lists; 2. Use extend method, which is efficient but will modify the original list; 3. Use itertools.chain, which is suitable for large data sets; 4. Use * operator, merge small to medium-sized lists in one line of code; 5. Use numpy.concatenate, which is suitable for large data sets and scenarios with high performance requirements; 6. Use append method, which is suitable for small lists but is inefficient. When selecting a method, you need to consider the list size and application scenarios.

Python: For and While Loops, the most complete guideMay 09, 2025 am 12:05 AMIn Python, a for loop is used to traverse iterable objects, and a while loop is used to perform operations repeatedly when the condition is satisfied. 1) For loop example: traverse the list and print the elements. 2) While loop example: guess the number game until you guess it right. Mastering cycle principles and optimization techniques can improve code efficiency and reliability.
Python concatenate lists into a stringMay 09, 2025 am 12:02 AMTo concatenate a list into a string, using the join() method in Python is the best choice. 1) Use the join() method to concatenate the list elements into a string, such as ''.join(my_list). 2) For a list containing numbers, convert map(str, numbers) into a string before concatenating. 3) You can use generator expressions for complex formatting, such as ','.join(f'({fruit})'forfruitinfruits). 4) When processing mixed data types, use map(str, mixed_list) to ensure that all elements can be converted into strings. 5) For large lists, use ''.join(large_li

Python concatenate lists with duplicatesMay 08, 2025 am 12:09 AMIn Python, you can connect lists and manage duplicate elements through a variety of methods: 1) Use operators or extend() to retain all duplicate elements; 2) Convert to sets and then return to lists to remove all duplicate elements, but the original order will be lost; 3) Use loops or list comprehensions to combine sets to remove duplicate elements and maintain the original order.
