Largest Quantity Groupings in String in Python

The problem

You might be be given a string that has lowercase letters and numbers. Your job is to match the quantity groupings and return the biggest quantity. Numbers is not going to have main zeros.

For instance, clear up("gh12cdy695m1") = 695, as a result of that is the biggest of all quantity groupings.

The answer in Python code

Choice 1:

import re
def clear up(s):
    return max(map(int,re.findall(r"(d+)", s)))

Choice 2:

def clear up(s):
    return max(map(int,"".be part of(" " if x.isalpha() else x for x in s).cut up()))

Choice 3:

def clear up(s):
    i, maxn, L = 0, 0, len(s)
    numStart = False
    whereas i < L:
        if s[i].isdigit():
            j = i+1
            whereas j<L and s[j].isdigit():
                j += 1
            if int(s[i:j]) > maxn:
                maxn = int(s[i:j])
            i = j+1
            i += 1
    return maxn
