Why does the following not work? if letter == ('O' or 'Q'): statement

It only does the ststement if 'O' is true, not if 'Q' is true.

In this way you are trying to compare the letter variable already to the boolean result of the or statement. So you tell Python to check if letter == True, not if it is equal to any of those chars. You should either decompose it like Valentin suggested or use the 'in' phrase: if letter in ['Q', 'O']: statement It is more flexible because you can easily add consecutive letters only and not another 'or letter==' phrase.

That worked, but i dont understand why the first only evaluates the first letter.
