how to comment out many lines in python code example

Example 1: python comment multiple lines

#There is no way to comment multiple lines in Python.
#You just keep using "#" symbol to comment each line out.

'''
Technically you could also use triple single quotation
marks like so, but this formatting does not count
as "true" source code comments that are removed by
a Python parser.
'''

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: comment all selected lines in python
