Behavior when writing functions in Python

[minhduc0711]

I'm having this problem in Python when I write functions arguments like this ( | indicates the cursor position)

def do_something(a,|

When pressing Enter:

Expected

def do_something(a,
                |):

where the auto indentation is already handled by a Python vim plugin.

Actual

def do_something(a,
    |
                 )

Would be great if you can improve this, as I love bracket auto expansion. Thanks!
