A = [s for s in A if s.strip()]

The above code works because empty strings - ie '' - evaluate to False.

A = [s for s in A if s.strip() != '']

or

A = [s for s in A if len(s.strip()) > 0]

Because empty strings '' evaluate to false you can simplify even more; A = [s for s in A if s.strip()] – spencer.pinegar Jul 28 '21 at 23:21
