def sumDigit(string):
    sum = 0
    for a in string:
    #Checking if a character is digit and adding it
        if(a.isdigit()):
            sum += int(a)
    return sum

userInput = input("Enter any string with digits: ")

#Calling the sumDigit function
result = sumDigit(userInput)

#Printing the sum of all digits
print("The sum of all digits in the string '",userInput,"' is:",result)

OUTPUT:
