Python course Ch 4 - flow control

[Piotr]

Hello,

I'm following video, and for some reason IF statement doesn't work properly:

def flow_control():
    answer = input("Do you want to learn about multiline text strings? (yes or no)")
    #if answer == "yes" or answer == "y":
    if answer == ("yes" or "y"):
        display_lesson()
    else:
        use_time()
        print("End program")

Commented out IF statement works perfectly well, but 2nd one work only for "yes".

How can i make it work?

Looks like a line-break issue ... or indentation. 

Be sure the IF the block is properly indented.

i'm using PyCharm, in such cases i have red underline and code would not run properly.

I replaced tabs with 4 spaces, but it did not help at all.

    if answer == ("y" or "yes"):
        display_lesson()

I have replaced "y" with "yes" so answer is True only for "y" because for "yes" it going to else statement.

It looks my IDE does not consider "or".

PS. i was fooling around and changed or to and. In that case for answer is True for "yes".

Anyhow ill back to version without parentheses, just was curious what is going on in background.
