Question

Write a Python function, called counting, that takes two arguments (a string and an integer), and returns the number of digits in the string argument that are not the same as the integer argument. Include a main function that inputs the two values (string and integer) and outputs the result, with appropriate labelling.

You are not permitted to use the Python string methods (such as count(), etc.).

Sample input/output:

Please enter a string of digits: 34598205
Please enter a 1-digit value: 5
The number of digits that are not 5 is 6

Answer 1

def counting(string, num):
    answer = 0
    for i in string:
        if int(i)!=num:
            answer += 1
    return answer

def main():
    s = input("Please enter a string of digits: ")
    i = int(input("Please enter a 1-digit value: "))
    print("The number of digits that are not",i,"is",counting(s,i))

main()

$\color{blue}\underline{Output:}$

Please enter a string of digits: 34598205 Please enter a 1-digit value: 5 The number of digits that are not 5 is 6 Process finished with exit code 0,
