and thanks for help

That's a series of function definitions rather than a main program (no, wait, I see some main code mixed in!) ... and I fear that some of the spacing that's vital to Python has been lost or damaged. Can you give us an example of how it runs, anc check the spacing?

oh yes.. sorry i messd some thing;
i have this code by searching for some thing that make some spell checking by php without no addons.
and finally i found this code but in python so i ask for help from any one who have any idea about python
so any help is welcome...
-- the use of this code as follow:
      Code:

>>> correct('speling') 'spelling' >>> correct('korrecter') 'corrector'

thats all
and thanks for help......
and sorry for any miss understanding i think we are all here for help..

If you're not familiar with Python but know PHP, perhaps the following resources would be helpful:
