This is needlessly dependent on the content of the opening line; if that changes, the rest need to change. It begs for the indentation to get mis-aligned when other lines are edited.
# 4-space hanging indent; nothing on first line foo = long_function_name( var_one, var_two, var_three, var_four)
This one doesn't have the previous problem, which is why it's what I recommend. I would be happy to see the latter explicitly recommended in PEP 8. If the price of that is to have the former also recommended, I'd grumble but it would be an improvement.
No: # Stuff on first line forbidden foo = long_function_name(var_one, var_two, var_three, var_four)
# 2-space hanging indent forbidden foo = long_function_name( var_one, var_two, var_three, var_four)
I agree with pointing to both of these as bad examples. -- \ “People demand freedom of speech to make up for the freedom of | `\ thought which they avoid.” —Soren Aabye Kierkegaard (1813–1855) | _o__) | Ben Finney
