How can I work with an if statement and an input? [duplicate]

I've cracked my head for 2 hours without result. I tried changing the code but i don't understand what's wrong:

if input("Are you a male or female?: ") == "male" or "Male":
    isMale = True
else:
    isMale = False

if input("Are you tall or short? ") == "tall" or "Tall":
    isTall = True
else:
    isTall = False

if (isMale is True) and (isTall is True):
    print("You are a tall male")
elif (isMale is False) and (isTall is False):
    print("You are a short female")
elif (isMale is True) and (isTall is False):
    print("You are a short male")
elif (isMale is False) and (isTall is True):
    print("You are a tall female")`

Whatever I input it's just "You are a tall male" I do not understand why. Thank you in advance :)
