I'm just writing a simple if statement. The second line only evaluates to true if the user types "Good!" If "Great!" is typed it'll execute the else statement. Can I not use or like this? Do I need logical or?
weather = input("How's the weather? ")
if weather == "Good!" or "Great!": print("Glad to hear!")
else: print("That's too bad!")1 Answer
You can't use it like that. The or operator must have two boolean operands. You have a boolean and a string. You can write
weather == "Good!" or weather == "Great!": or
weather in ("Good!", "Great!"): What you have written is parsed as
(weather == "Good") or ("Great")In the case of python, non-empty strings always evaluate to True, so this condition will always be true.
