You top-posted, instead of putting your response after whatever you were 
quoting.  So you lose all context.

Your code won't compile, and it's unclear just what you were trying to 
accomplish.  What do you mean by "the right way"?

Please post the actual code that you're running, and explain what you 
expected, what you got, and how it didn't do what you wanted.  In this 
case, you should give us the traceback, so it's obvious that you're 
trying to figure out how to indent.
