Shallow Copy vs Deep Copy

In this section, we’ll learn how to copy the objects in Python. You must have heard the terms shallow copy and deep copy before.

Alert: Just a heads up that for primitive types (int), there’s no difference between a shallow copy and a deep copy.

Python’s built-in mutable objects can be copied by using their constructor. For example:

l2 = list(l1)  # List l1 copied with list()
d2 = dict(d1)  # Dictionary d2 copied with dict()
s2 = set(s1)   # Set s2 copied with set()
