Vim Python completion

pythoncomplete is rather old and unmaintained.

Try to use Jedi: https://github.com/davidhalter/jedi-vim
It was originally an improved pythoncomplete, but is now much much more powerful!

It works for complex code:

And has additional features:

There is a list of all possible features:

• builtin functions/classes support
• complex module / function / class structures
• ignores syntax and indentation errors
• multiple returns / yields
• tuple assignments / array indexing / dictionary indexing
• exceptions / with-statement
• *args / **kwargs
• decorators
• descriptors -> property / staticmethod / classmethod
• closures
• generators (yield statement) / iterators
• support for some magic methods: __call__, __iter__, __next__,
  __get__, __getitem__, __init__
• support for list.append, set.add, list.extend, etc.
• (nested) list comprehensions / ternary expressions
• relative imports
• getattr() / __getattr__ / __getattribute__
• function annotations (py3k feature, are ignored right now, but being parsed.
  I don’t know what to do with them.)
• class decorators (py3k feature, are being ignored too, until I find a use
  case, that doesn’t work with Jedi)
• simple/usual sys.path modifications
• isinstance checks for if/while/assert
