Program 33: Write a program that accepts a string as input and displays the count of alphabets, digits, and special
characters contained in it.

Ans. def countCharacters(string):

'''
Objective : To calculate count of alphabets, digits and special characters
in a sring
Input Parameter : string
Return Value : alphabetCount, digitCount, specialCount – numeric values
'''
# Initialize counters for alphabets, digits, and special characters
alphabetCount = digitCount = specialCount = 0

# Iterate through each character in the input string
for char in string:
if char.isalpha():
alphabetCount += 1

elif char.isdigit():
digitCount += 1
else:
specialCount += 1
return alphabetCount, digitCount, specialCount
