Strip all non-numeric characters (except for “.”) from a string in Python

Question

I\'ve got a pretty good working snippit of code, but I was wondering if anyone has any better suggestions on how to do this:

val = \'\'.join([c for c in val          


        

Answer 1

Another 'pythonic' approach

filter( lambda x: x in '0123456789.', s )

but regex is faster.
