Fold / Collapse the except code section in sublime text 2

Question

Is there any plugin or shortcut to hide all except code section in sublime text 2?

I need to fold all except section at a time , Not fold one section at a time.

Answer 1

One thing you can do is select the Except code bloc using a regular expression, for instance using except(.|\n)*?raise.* in your case. You can then select "Find all" in the search bar, then Edit->Code Folding -> Fold .
Windows shortcut : Ctrl-Shift-[
Mac shortcut: Cmd-Alt-[

All the Except bloc will then be collapsed.
