Longest consecutive substring of certain character type in python

Question

Is there a pythonic way to find the length of the longest consecutive substring of a certain character type, for instance the length of the longest consecutive substrings of dig

Answer 1

If there are always "**" between each substring. All you have to do is iterate over the different elements, keeping in a variable the longest substring you have found so far.

longest_letter = 0
longest_digit = 0
for el in s.split("**"):
    if(el.isalpha()):
        len_letter = len(el)
        if(len_letter > longest_letter):
            longest_letter = len_letter
    if(el.isdigit()):
        len_digit = len(el)
        if(len_digit > longest_digit):
            longest_digit = len_digit
print (longest_letter)
print (longest_digit)
