Sum of digits in a string

Question

if i just read my sum_digits function here, it makes sense in my head but it seems to be producing wrong results. Any tip?

def is_a_digit(s):
\         


        

Answer 1

I would like to propose a different solution using regx that covers two scenarios:

1.
Input = 'abcd45def05'
Output = 45 + 05 = 50

import re
print(sum(int(x) for x in re.findall(r'[0-9]+', my_str)))

Notice the '+' for one or more occurrences

2.
Input = 'abcd45def05'
Output = 4 + 5 + 0 + 5 = 14

import re
print(sum(int(x) for x in re.findall(r'[0-9]', my_str)))
