python copy class instance code example

Example 1: python copy instance

import copy

class A(object):
  def __init__(self, a)
  	self.a = a

a = A(38)

# Deepcopy
a2 = copy.deepcopy(a)

# Shallow copy -> use this if copy.deepcopy() fails
a3 = copy.copy(a)

Example 2: call instance class python

# define class
class example:
# define __call__ function
   def __call__(self):
       print("It worked!")
# create instance
g = example()
# when attempting to call instance of class it will call the __class method
g()
# prints It worked!
