To be fair, in the same section[1] that example is given, it also
suggests
# More indentation included to distinguish this from the rest.
def long_function_name(
var_one, var_two, var_three,
var_four):
print(var_one)
# Hanging indents should add a level.
foo = long_function_name(
var_one, var_two,
var_three, var_four)
both of which can be done with arbitrary indentation without the need
to mix tabs+spaces or use a non-integer multiple of
indentation-spaces. I just use these two in all instances and (as
you, Greg, advise), "cheerfully ignore [the first form]"
The only time I intentionally violate the "don't do these" section
"""
# Arguments on first line forbidden when not using vertical alignment.
foo = long_function_name(var_one, var_two,
var_three, var_four)
"""
is when defining options in optparse:
parser.add_option("-v", "--verbose",
help="be prolix",
action="store_true",
dest="verbose",
default=False,
)
as I find that a little easier to read when I'm scanning large blocks
of parser.add_option(...) calls, having the option stick out to the
right.
