How do you write a Python program that accepts a string and calculate the number of digits and letters?
Take an input string. While iterating over the whole string, if we find a digit, then increment the count of digits; otherwise, if we find a letter, then increment the count of letters. Return the count of letters and digits as the output.
How do you find the number of digits in a string?

How do you split a string between letters and digits in Python?
split(‘a’, ‘bbabbbab’) results in the list of strings [‘bb’, ‘bbb’, ‘b’] .
- # Method 1: re.split() import re. s = ‘111A222B333C’ res = re. split(‘(\d+)’, s)
- # Method 2: re.findall() import re. s = ‘111A222B333C’ res = re.
- # Method 3: itertools.groupby() from itertools import groupby. s = ‘111A222B333C’ res = [”.
