class - python className not defined NameError -

i have class need instantiate in order call method contains. when access class works fine when run terminal says :

  file "myclass.py", line 5, in <module>     class myclass:   file "myclass.py", line 23, in todict     td=myclass()     nameerror: name 'myclass' not defined 

pasting code:

class myclass:          def convert(self,fl):              xpd={}             # process stuff             return xpd  if __name__=="__main__":             source=sys.argv[1]             td=myclass()             needed_stuff=td.convert(source)             print needed_stuff 

looking @ indentation of code (and edit history of question), suspect if __name__ == "__main__" block inside of class definition. cause error, code within if run part of class being created, before class been bound name.

here's simpler example of error:

class foo(object):     foo = foo() # raises nameerror because name foo isn't bound yet 

if format code way looks in question (that is, if unindented @ top level), should work correctly.
