Solution Exercise 63: Python algorithm which determines the sum of digits within a given string

Exercise 63

Write a Python program that calculates the sum of digits numbers within a given string.

Solution

def digitSum(s):
    # initializing the sum of digits within the string s.
    sumDigit = 0
    
    # iterate over all characters of s:
    for x in s:
        if x.isdigit():
            
            # convert x into int type
            x = int(x)
            
            # adding x to sumDigit
            sumDigit = sumDigit + x
           
    return  sumDigit

#Testing algorithm:
s = "Python3.8 is more powerful than Python 2.7 "
print("The sum of digits within the string s is :" , digitSum(s))
# The output is : 
# The sum of digits within the string s is : 20
