My copy of pep 8 (from 2016) says:
Yes:
def f(x): return 2*x
. So this single-line style should not be that bad.
However, I remember someone saying that the multiline
style is more phytonic?
So, is this better:
def f(x):
return 2*x
Most of the time, yes. The whitespace on the left-hand side is a good
visual cue that something content-like is happening, in this case the
body of a function. The fact that it has shape makes it easier to
comprehend at a glance.
? And is
def f(x):
y = x*2
return y
better than
def f(x):
y = x*2; return y
Hell yes. One thought per line, please.
Something I keep repeating to clients is that whitespace is not the
enemy. Not even in C. Judicious use of spacing can make code *much*
easier to comprehend. Densely-written code makes you work hard to break
it down into manageable chunks; something as simple as the odd blank
line to "paragraph" your code can make that a lot easier.
Experience also suggests a correlation between code that's hard to read
and code that's rather crap.
