comment out a block of code in python code example

Example 1: python big comment

# one hashtag for a single line comment

"""
3 quote marks is technically
a docstring, but it works as
a multi line comment
"""

##pressing 'Alt 3' in IDLE comments out
##what you are selecting
and 'Alt 4' to uncomment

if False:
  print('Hello') # yes you can do it at the end of a line
  you can technically put if False around code you dont want it to run,
  but that would mean it has to have correct syntax,
  and would not be good for readability.

Example 2: comment out a block in python

select the lines you want to comment
and 'use Ctrl + / to comment all of the selected text'.
To uncomment do the same thing.
OR
put a '#' before each line

eg : #This is a comment

Example 3: python comment block

"""
this 
is
a multiline 
comment
"""

Example 4: comment sections of code python

For editing in VSCode, highlight code block, then: Edit>>Toggle Line Comment

Example 5: comment all selected lines in python

Select relevant lines to be commented, then use ctrl+/
