how can we write multi line comments

Answer 1

""" just
like
this """
(these are three double quotes, not six single)

Answer 2

Actually, these at the start of a function/class declaration will make it a docstring: that is a documentation inside Python.

So it's not really meant for it. Just use one # for each line if it is *not* for a docstring.

Answer 3

you can use three single quotes too

Answer 4

can we write comments in python like this?

Answer 5

yes, it's meant for it
