How do you comment multiple selected lines out all at once, without deleting them?

In a dunder method video, specifically dunder iterate, the teacher demonstrated commenting out two lines of code, while both selected at once with their own hashtag sign.

To comment out multiple lines of code at once, you can highlight them all and then press either cmd + / or ctrl + / depending on Mac or Windows.

This is what I was looking for. Maybe I should have been a bit more concise and elaborate. Thanks for you help, everybody. Megan's answer was the answer, that concisely answered my question.

Hi Luke Tate, To comment out a single line of code you would use the hash: # To comment out multiple lines of code you could either hash each line, or you could use three quotes before and after the lines of code. See below.

# This line of code is commented out
# This line of code is also commented out
name = Brandon # the name variable is declared and set, but this comment will be ignored
"""
All of this code
on these multiple lines
will be commented out
"""

Hope that helps. Good question.
