Which is preferred ("." indicating whitespace)?
A)
def foo():
x = 1
y = 2
....
if True:
bar()
B)
def foo():
x = 1
y = 2
if True:
bar()
My intuition would be B (that’s also what Vim does for me), but I see people using A) all the time. Is it just because most of the editors out there are broken?
The PEP 8 does not seem to be clear on this issue, although the statements about “blank lines” could be interpreted in favor of B. The PEP 8 style-checker (pep8.py) prefers B and warns if you use A; however, both variations are legal. My own view is that since Python will successfully interpret the code in either case that this doesn’t really matter, and trying to enforce it would be a lot of work for very little gain. I suppose if you are very adamantly in favor of one or the other you could automatically convert the one to the other. Trying to fix all such lines manually, though, would be a huge undertaking and really not worth the effort, IMHO.
