Python：我的其他语句中的语法无效

Question

I am starting out with Python and I just cannot figure out what I am doing wrong. This is an easy question for you to get a correct answer for!

Here is my code:

def statement(x):
    if x > 50:
        print("X is greater than 50")
    elif x < 50:
        print("X is lower than 50")
    else x == 50:
        print("X is 50")
    return

Very simple I know. When I try and run this, it returns an error saying invalid syntax regarding the X in my else statement:

Could anybody please point me in the correct direction as to what I am doing wrong?

Answer 1

You want elif not else , or you need to remove the condition from the else because else doesn't allow for a conditional statement.

if ...
elif x == 50:
    print("X is 50"

or

if ...
else:
    print("X is 50")

Answer 2

else does not take a conditional, like if or elif . If number isn't greater than 50 nor is it lesser than 50, it must be equal to 50:

if x > 50:
    print("X is greater than 50")
elif x < 50:
    print("X is lower than 50")
else: # no condition here!
    print("X is 50")
