'int' object has no attribute 'copy'

This error occurs when you try to use the copy() method on an integer (int) object in Python. The copy() method is not defined for integer objects, so Python raises an AttributeError.

To fix this error, you need to make sure that you are using the copy() method on the appropriate object. If you need to create a copy of an integer object, you can simply assign the integer value to a new variable. For example:

a = 5
b = a  # creates a copy of the integer value 5

If you are working with a different data type that does have a copy() method, such as a list or dictionary, make sure that you are using the method on the correct object.
