Python Coding challenge - Day 81 | What is the output of the following Python Code?

 

Code :

i=j=[3]

i+=j

print(i,j)

Solution and Explanation:

In this Python code:

i = j = [3]

i += j

print(i, j)

Both i and j are assigned the same list [3]. The += operator is used to extend the list i by appending the elements of list j to it.

After the execution of the code, the output will be:

[3, 3] [3, 3]

Here's the breakdown:

i = j = [3]: Both i and j are assigned the list [3].

i += j: The += operator modifies the list i by appending the elements of list j to it. So, i becomes [3, 3].

print(i, j): Prints the values of i and j.

As a result, both i and j are [3, 3].
