打狂犬疫苗不能吃什么

Question

First, I couldn't find an answer to this in PEP 8. That doesn't mean it isn't in there. Feel free to point me at it.

Which style do you prefer?

The first one:

if spam:
    # Do stuff.
    return eggs
else:
    # Maybe do other stuff.
    return parrots

or the second one:

if spam:
    # Do stuff.
    return eggs
# Maybe do other stuff.
return parrots

Answer 1

It depends, if you would return parrots, when you do not return eggs, then the first one is more clear. But if you are trying to catch an error or something like that, the second one is better.

Answer 2

The first one!

Explicit is better than implicit.

Answer 3

The second one! Less is more, and more is better.

Answer 4

It doesn't really matter. If you really need reasons for picking one, use the one that best conveys the reasons behind the code. The first one if both cases are somehow similar or equally important. The second one if you usually return parrots but eggs is a special case.

Answer 5

The second one. The same applies not only to return but also to break and continue statements. The else and the consequent indentation are eye-irritating and a waste of space.

Answer 6

Neither!

if spam:
    # Do Stuff
    result= eggs
else:
    # Maybe do other stuff
    result= parrots
return result

Answer 7

I think it depends on the "do stuff" part. Both are acceptable.

Answer 8

I don't know python, but I do :

return spam if eggs else parrots

Edit : I didn't notice the Do stuff part. In that case, I would create another method or function (whatever it is called in python) for each branch.
