Hi, does anybody know how to determine whether an input string (from raw_input) is a float? I know isdigit() works for int types, but what of float types? Or, is the only solution converting the string to a float(),and then assuming the program will crash for non-float input values?

You could do something like: try: x = float( raw_input( "> " ) ) except: #handle it not being a float
Thanks, this is pretty much what I'm going to do. I just wasn't sure if there was a built in function like isdigit()
There are always regular expressions. "\d*\.?\d*" off the top of my head.
