python copy instance code example

Example 1: python clone object

import copy

new_ob = copy.deepcopy(old_ob)

Example 2: 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 3: .copy python

new_list = list.copy()

# returns a new list without modifying the orginal list.
