How To Comment Out Multiple Lines in Python

Commenting out multiple lines in Python is useful for temporarily disabling code or adding explanations and documentation. Python does not have a built-in way to comment out multiple lines directly, but there are a few techniques and tools you can use:

Techniques:

1. Using # for Each Line:
   Manually place a # at the beginning of each line you want to comment out.

   # print("This is a line of code")
   # print("This is another line of code")

2. Using Triple Quotes:
   Use triple quotes (""" or ''') to create a multi-line string that is not assigned to any variable. This method is not recommended for commenting out actual code as it can be confused with docstrings.

   """
   print("This is a line of code")
   print("This is another line of code")
   """

Tools and Shortcuts:

1. VSCode:

• Using # for Each Line:
  • Highlight the lines you want to comment.
  • Press Ctrl + / (Windows/Linux) or Cmd + / (Mac).
  • Example:
    python # print("This is a line of code") # print("This is another line of code")

2. Keyboard Shortcut (General):

• The Ctrl + / or Cmd + / shortcut works in most modern IDEs and text editors to toggle comments for selected lines.

3. Sublime Text:

• Highlight the lines you want to comment.
• Press Ctrl + / (Windows/Linux) or Cmd + / (Mac).
• Example:
  python # print("This is a line of code") # print("This is another line of code")

4. Jupyter Notebooks:

• Highlight the lines you want to comment.
• Press Ctrl + / (Windows/Linux) or Cmd + / (Mac).
• Example:
  python # print("This is a line of code") # print("This is another line of code")

Live Examples:

VSCode:

# print("This is a line of code")
# print("This is another line of code")

General Keyboard Shortcut:

# print("This is a line of code")
# print("This is another line of code")

Sublime Text:

# print("This is a line of code")
# print("This is another line of code")

Jupyter Notebooks:

# print("This is a line of code")
# print("This is another line of code")

Using these techniques and shortcuts can significantly improve your efficiency in commenting out multiple lines of code in Python across various environments.
