Number within range

[Larz60+]

A better way to write this:

def get_int(itext):
    num = None
    while not isinstance(num, int):
        try:
            value = input(f'{itext}: ')
            num = int(value)
        except ValueError:
            print('Please -- integers only')
    return num

def main():
    number = get_int("Enter number")
    start_of_range = get_int("Enter start of range")
    end_of_range = get_int("Enter end of range")


if __name__ == '__main__'
    main()

test:

Output:
Enter number: Jimbo
Please -- integers only
Enter number: 45.2
Please -- integers only
Enter number: 15
Enter start of range: 7
Enter end of range: 14
