When i have something like:
```
if a:
    r = do_something(a)
else:
    r = do_something_else()
return r
```

my preference goes to:
```
if a:
    return do_something(a)
return do_something()
```

I'd even prefer to do that but i had surprises at some point with that (probably python's strictness i need to check):
```
return do_something(a) if a else do_something()
```
