Python comment multiple lines shortcut Mac

A great question!

When working with Python comments on a Mac, there are a few ways to comment out multiple lines of code. Here's the scoop:

Method 1: Using # symbol

One way is to use the # symbol at the beginning of each line you want to comment out. For example:

# This is a comment on line 1
This is another comment on line 2
print("Hello, World!")

This works just fine, but it can be tedious to write the # symbol at the start of each line.

Method 2: Using triple quotes ''' or """

A more efficient way is to use triple quotes (''') or double quotes ("""). This will comment out all lines between the opening and closing quotes:

'''
This is a comment on line 1
This is another comment on line 2
print("Hello, World!")
"""

When you want to comment out only a few lines, this method is much quicker than typing # for each line.

Method 3: Using the # symbol followed by a newline character

If you prefer a single-line solution, you can use the # symbol at the beginning of a line, followed by a newline character (n). This will comment out all lines until you encounter another newline character:

# This is a comment on line 1
print("Hello, World!")

In this example, everything between the first # and the next # is commented out.

Bonus Tip: If you want to comment out multiple lines of code in an existing Python file without affecting the code's functionality, you can use a text editor or IDE (Integrated Development Environment) with Python syntax highlighting. This will help you visually identify the comments and ensure they don't interfere with your code's execution.

In summary, when commenting out multiple lines of code in Python on a Mac, you have three options:

Choose the method that suits your coding style best!

Python comment multiple lines shortcut Spyder

To respond in English only, I'll make sure to keep my responses clear and concise.

Regarding your question about the shortcut for commenting multiple lines in Spyder, a popular Python IDE, you're in luck! The shortcut is Ctrl + Shift + # (Windows) or Cmd + Shift + # (Mac).

When you press this shortcut combination, it will add a # symbol at the start of each line, effectively commenting out the selected text. You can use this feature to quickly comment out multiple lines of code in Spyder.

Here's how it works:

Alternatively, if you're using Spyder 4.x or later, you can also use the built-in "Block comment" feature by pressing Ctrl + Shift + Alt + C (Windows) or Cmd + Shift + Opt + C (Mac).

This feature will automatically add comments to your selected text, including multiple lines, without requiring you to manually wrap each line with a # symbol. Simply select the block of code and press the shortcut, and Spyder will do the rest!

Both of these shortcuts make it easy to comment out or uncomment large blocks of code in Spyder, saving you time and effort.

Hope that helps!
