How to shorten 'if, else' statement in python?

Question

I'd like to shorten my if, elif, else statement, Here's what it looks :

transparency == False
if transparency == 'true':
    transparency = True
elif transparency == 'false':
    transparency = False
else:
    transparency = True

And here's what I tried :

transparency == False
transparency == 'true' ? True: False #boolean type

I thought it'd work like the javascript shorthand, am I wrong?

You are overcomplicating things. The value is False only if originally equal to 'false', True for anything else:

transparency = transparency != 'false'

You otherwise got your Javascript syntax mixed up with Python; the Python conditional expression syntax is spelled

<true_expr> if <test> else <false_expr>

I knew I was overcomplicating things that's why I was wondering how I could do it in one line :)

Basically, if transparency is anything other than 'false', it's going to be True. So…

transparency = transparency != 'false'

"'id like to shorten my if, else if, else statement," You broke his concept by assuming his logic.

This is the logic OP's code expresses. The result is exactly the same.

@RoyHolzem The answer is a one liner that works in all context, it does respect my logic.
