Remove whitespace in Python using string.whitespace

Question

Python's string.whitespace is great:

>>> string.whitespace
'\t\n\x0b\x0c\r '

How do I use this with a string without resorting to manually typing in '\t|\n|... etc for regex?

For example, it should be able to turn: "Please \n don't \t hurt \x0b me."

into

"Please don't hurt me."

I'd probably want to keep the single spaces, but it'd be easy enough to just go string.whitespace[:-1] I suppose.

Answer 1

There is a special-case shortcut for exactly this use case!

If you call str.split without an argument, it splits on runs of whitespace instead of single characters. So:

>>> ' '.join("Please \n don't \t hurt \x0b me.".split())
"Please don't hurt me."
