Remove all whitespace in a string

Question

I want to eliminate all the whitespace from a string, on both ends, and in between words.

I have this Python code:

def my_handle(self):
    sentence          


        

Answer 1

Be careful:

strip does a rstrip and lstrip (removes leading and trailing spaces, tabs, returns and form feeds, but it does not remove them in the middle of the string).

If you only replace spaces and tabs you can end up with hidden CRLFs that appear to match what you are looking for, but are not the same.
