Check if a string contains a number

Question

Most of the questions I\'ve found are biased on the fact they\'re looking for letters in their numbers, whereas I\'m looking for numbers in what I\'d like to be a numberless

Answer 1

I'm surprised that no-one mentionned this combination of any and map:

def contains_digit(s):
    isdigit = str.isdigit
    return any(map(isdigit,s))

in python 3 it's probably the fastest there (except maybe for regexes) is because it doesn't contain any loop (and aliasing the function avoids looking it up in str).

Don't use that in python 2 as map returns a list, which breaks any short-circuiting
