- Using or in if statement (Python) - Stack Overflow
The left part may be false, but right part is true (python has "truth-y" and "fals-y" values), so the check always succeeds The way to write what you meant to would be if weather == "Good!" or weather == "Great!": or (in more common python style) if weather in ("Good!", "Great!"):
