[Manprit Singh]

Dear sir,

Correcting the function written for the problem :
Problem to extract a numeric suffix from a string

def ret(st):
    for x, y in enumerate(reversed(st)):
        if not y.isdigit():
            return st[-x:] if x else "No digit suffix found"
    return st

Anything more readable in comparison to this function be done ? Kindly
