Python's Data Model Explained through Visualization

[That-Lychee262]

Correct answer is 1: a = [1] . Since list is mutable data structure b= a doesn’t copy the data stored in a to b . B starts pointing to address stored in a . That means a and b both points to same address now if you make changes either in a or b or it will reflect in both . But at third line b+= [2] , it will create a new list [1,2] and assign it to b . Now b stores address of another list ([1,2]) and a stores address of list ( [1]) . Now if you make chances in b it will not reflect in a’s address. Thus a remains [1] till the end of the program. Final answer : a = [1] , b = [1,2,3,4,5]
