Question

Forms often allow a user to enter an integer. Write a program that takes in a string representing an integer as input, and outputs yes if every character is a digit 0-9.

Ex: If the input is: 1995 the output is: yes

Ex: If the input is: 42,000 or any string with a non-integer character, the output is: no

Answer 1

# ask the user to input a string

user_string = input("Enter your string : ")

# check whether the input entered by the user have all value as numeric or not

# if all value are numeric then True is stored in Result otherwise False is stored in Result

Result = user_string.isnumeric()

# if the entered string contains all numeric values

if Result == True:

    print("yes")

# if the entered string contains at least one non - integer character

else:

    print("no")
