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.

text = input("enter a value: ")

if text.isdigit():

       print("yes")

Explanation:

The program is written in python.

text = input("enter a value: ")  This expression prompt the user to input  a string value containing any form of character . The inputted character might be letters, digits etc.

if text.isdigit():

This check if the inputted value is a digit .

print("yes")

if the value is a digit the system will display yes.
