Python Coding Challenge - Question with Answer (ID 221026)

 

Explanation:

1. Creating a List

a = [1, 2]

- A list containing two elements, 1 and 2, is created.

- The variable a refers to this list.

Current list:

[1, 2]

2. Understanding a * 2

a * 2

In Python, multiplying a list by an integer repeats its elements that many times.

So, [1, 2] is repeated twice.

[1, 2, 1, 2]

Result: [1, 2, 1, 2]

3. Understanding a + a

a + a

The + operator concatenates two lists, joining their elements into one new list.

First list: [1, 2]

Second list: [1, 2]

Combined result:

[1, 2, 1, 2]

Result: [1, 2, 1, 2]

4. Understanding the Equality Operator ==

a * 2 == a + a

Python compares the two resulting lists:

[1, 2, 1, 2] == [1, 2, 1, 2]

- Both lists contain the same elements.

- The elements appear in the same order.

- Therefore, the comparison returns True.

5. Final Output

True
