Compare if two variables reference the same object in python

Question

How to check whether two variables reference the same object?

x = [\'a\', \'b\', \'c\']
y = x                 # x and y reference the same object
z = [\'a\', \'b         


        

Answer 1

This is from docs.python.org: "Every object has an identity, a type and a value. An object’s identity never changes once it has been created; you may think of it as the object’s address in memory. The ‘is’ operator compares the identity of two objects; the id() function returns an integer representing its identity."

Apparently every time you change the value the object is recreated as indicated by the identity changing. The line x=3 followed by the line x=3.14 gives no error & gives different identities, types and values for x.
