What is wrong with my loop? Absolute beginner

Question

while True:
    COLOR = input('Please enter green or blue: (green/blue) ').lower()
    if COLOR == 'blue' or 'green':
        print('correct!')
        break
    else:
        print('Please enter green or blue.')
        continue

Terminal: Please enter green or blue: (green/blue) asdfasefase correct!

even though the input does not match the variable it still is true, why?

or 'green' is always true. it's a none zero sequence of characters. you need to write it as COLOR=='blue' or COLOR=='green'. or just simply COLOR in ('green', 'blue'). — aSaffary, May 14 '22 at 09:16
Modify the `if` statement to `COLOR == blue or COLOR == green` — Geeky Quentin, May 14 '22 at 09:16
`COLOR == 'blue' or 'green'` is the same as `(COLOR == 'blue') or ('green'`)`. — Some programmer dude, May 14 '22 at 09:21

your if statement is wrong. It needs to be:

if COLOR == 'blue' or COLOR == 'green'

in your case or 'green' will always be interpreted as true hence anything will be correct
