Question

Ex 1.8 (pt.4) I can't figure out how to stay IN a while loop on an incorrect input by the user. I kept having the loop stop, or go on for ever. In the end i just used a recursive function! (but we've not covered functions yet..so thats a bit like cheating!)

Answer 1

Hi there,

What i did was to set a variable equal to 1 and then took user input into that var. Then my while loop was simply:
while var % 2 != 0:
var = input ("please type an even number : ")

Hope this helps.

@andrew.m.higgs
Thanks Andrew. Worked just fine!
I couldn't quite get my head around looping back upon a False input. I kept thinking "surely it needs another condition to test against?"
But your reply showed me how simple it was! :0)

Pleasure. :-)
