Python: how to substitute and know whether it matched

Question

I know that re.sub(pattern, repl,text) can substitute when pattern matches, and then return the substitute.

My code is:

text = re.sub(p         


        

Answer 1

"Whether string contains numbers":

for text1 in ('abc123def', 'adsafasdfafdsafqw', 'fsadfoi81we'):
    print("Text %s %s numbers." %
          ((text1, )  + (
              ('does not contain',) if not any(c.isdigit() for c in text1)
               else ('contains',))
           ))
