PyCharm autocomplete

Question

I'm completely new to Python and PyCharm and I cannot figure out why PyCharm doesn't auto-completes very simple cases such as:

import pickle

pickle.dum[control+space or control+shift+space results nothing here]

I have PyCharm 2.6.2 and Python 2.7.1. What's wrong?

Add:

I'm on Mac OS 10.7.3

Answer 1

It happened to me, too. But all the previous answers don't solve my issue.

The weird thing is when I am coding, it will pump out the autocomplete for me. But once I leave the autocomplete mode, I cannot reproduce the autocomplete by typing Ctrl + Space.

So the work I already surveyed are

1. Make sure the config(e.g., virtualenv) is right in Pycharm
2. Make sure Pycharm can show autocomplete
3. Make sure I am not in the Power Safe Mode

Finally I solved this just because my shortcut of switch language in the Mac is also Ctrl + Space, so it's kind of override my shortcut in the Pycharm. I change the shortcut in the Pycharm by changing in Pycharm-> Preference-> Keymap-> Main menu-> Code-> Completion ->Basic

Then the problem is solved

Answer 2

My experience is if you turn ON the File -> Power-Save Mode, all background tasks will be stopped, including the Auto-Complete task. So you can try turning off the Power-Save Mode.

I changed the projector interpreter and it works fine now.

Answer 4

You could try with a virtualenv and on it install all you project dependencies and the go to pycharm preferences/Project Interpreter and it will update your project dependencies.

Answer 5

Can't reproduce. Make sure you have a valid Python interpreter configured for the project. Also try File | Invalidate Caches.
