Python等效于选择第一个非null参数

Question

In JavaScript I can do

const foo = bar || baz || bloop || blop || bleep || null

If I want foo to be equal to the first one of the above arguments that is not falsey / null

Is there an idiomatic Python equivalent? I was just going to loop through a list of args, but thought I'd check.

@zvone is correct. For instance:

banana = True
tom = 4
hotdog = None
goo = hotdog or tom or banana
shazam = banana or hotdog or tom

In this example, goo is 4 , and shazam is True . So you can mix types! Cool stuff.
