Python - Same variable in if statement

Question

Is there a shorter form for something like:

if v or v == 0:

v can be None or an int. If it is not None or 0, go in.

You can use if v ? (but your code example contradicts your explanation somewhat...) — Jon Clements

I don't believe you will be able to get shorter than that. You have 2 very different conditions. — user2097159

What about:

if v is not None:
    # code

To test it:

l = [None, 0, 13, -123]

for i in l:
    if i is not None:
        print i

Ouput:

0
13
-123

Difficult to tell what the OP is really after, but this doesn't quite match If it is not None or 0, go in.

None and 0 all represent false, other int except zero are represent true. If you just don't want false,you can use：

if not v:
     pass

if not v is when it is false - the opposite of If you just don't want false
