1. Always post the actual code - the code you posted is not valid
Python as many colons (:) are missing.
2. You appear to be attempting to use the same name (copy) both as a
method name AND as a local variable of that method.  This definitely
look wrong.

Perhaps if you could post the actual offending code (the smallest
example showing the problem you observe) others might be able to help
