User inputted integer using while statement

Question

Ok need to understand why my code is not working. At the moment it's getting stuck in a infinite loop of asking the user for a pin after a wrong pin is inputted.

I believe I'm screwing up the while statement somehow.

def inputValidator():
    userInput = requestInteger("Please input a PIN between 1 - 1000")
    while 1 > userInput > 1000 : 
        requestInteger("Your PIN is not within 1 - 1000, please try again")
    print("Thanks! your new PIN is " + str(userInput))

thanks for the help guys!

Try this:

def inputValidator():
    userInput = requestInteger("Please input a PIN between 1 - 1000")
    while userInput<1 or userInput>1000:
        userInput = requestInteger("Your PIN is not within 1 - 1000, please try again")
    print("Thanks! your new PIN is " + str(userInput))

You'll want a new input from your user if userInput is smaller than 1 or bigger than 1000 - and like @Polina F. said - you didn't assign a new value to userInput inside the while loop. This is why it loops for ever.

You don't assign nothing in the while loop. userInput never gets updated - hence you can't exit the loop

you aren't assigning requestInteger to userInput

while 1 > userInput > 1000 : 
  userInput =requestInteger("Your PIN is not within 1 - 1000, please try again")
