No autocomplete for some standart libraries

Hello,

I just started to use pyCharm.

And get strange behavior of IDE.

When type this code

import socket

s = socket.socket(socket.AF_INET, socket.SOCK_STREAM)

s.

and press Ctrl+Space to see addtition methods, i didn't see any need methods such as connect(), recv(), send() and other

Where could be a problem?

is it a bug or i have misconfigured IDE?

i use Ubuntu 12.04 with python3.2
