Answer 1

Your timestamp format has colons in it, which are not allowed in Windows filenames. See this answer on that subject:

How to get a file in Windows with a colon in the filename?

If you change your timestamp format to something like:

timestamp = str(now.strftime("%Y%m%d_%H-%M-%S"))

it should work.

Answer 2

you can't have : as part of the filename

change

timestamp = str(now.strftime("%Y%m%d_%H:%M:%S"))

to

timestamp = str(now.strftime("%Y%m%d_%H%M%S"))

and you'll be able to rename your file
