Prompt for a value in a range

Question

Write a program that asks the user to enter the number of push-ups they can do. The program should force the user to enter a valid number by repeating the question until a number between 0 and 500 is entered. Once a valid answer is provided, the program should print out: “Wimp!! I can do X.” where X is one more that what the user entered.

This is what the shells shows:

How many push-ups can you do? 1000
Liar, please enter a number between 0 and 500: 2341
Liar, please enter a number between 0 and 500: 75
Wimp!! I can do 76.

i tried in on the python command: print " How many push-ups can you do? " pushups = float(raw_input()) while not(pushups >= "0" or pushups <= "500"): print " Liar, please enter a number between 0 and 500: " pushups = float(raw_input()) if (pushups >= "0" or pushups <= "500" ): print " Wimp!! I can do " + str(pushups) — Mikias Debesay, Feb 08 '18 at 15:26

This should do the job:

while True:

    answer = int(input("How many push ups can you do?\n"))

    if answer > 500 or answer < 0:
        print("Liar, please enter a number between 0 and 500:")
        continue
    else:
        print("Wimp!! I can do {x}.".format(x = answer + 1))
        break

It's hard to tell if all the statements are contained in the while loop. If they are: Then nothing, not even the wimp part, will be printed when the value is in the correct range because the condition of the while loop will not be met. The condition of the while loop is only met when the number is out of range. – Gab Feb 08 '18 at 15:57
