Anyway to bring up suggestion box when typing python code

I'm learning wxpython right now and one thing that helps me ALOT is when I'm typing in the text editor I sometimes press the tab key to give me a hint on what I'm looking for...This is great when it works but I notice sometimes it doesn't work and I get lost looking for a syntax I can't remember...

Question is how can I get the suggestion box to pop back up again, Or what am I doi开发者_JAVA百科ng that causes it to stop coming up...

if it matters I backtracked to 2.7 to learn wx, Windows 7

Edit: More specifically... when I type: wx.(Here is normally when I would press tab)

What editor do you use??

Without knowing that there's no way we can possibly help you.

FWIW in vim I use C-x [onp]
