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

What about this one?

import string

def containsNumber(line):
    res = False
    try:
        for val in line.split():
            if (float(val.strip(string.punctuation))):
                res = True
                break
    except ValueError:
        pass
    return res

containsNumber('234.12 a22') # returns True
containsNumber('234.12L a22') # returns False
containsNumber('234.12, a22') # returns True
