Lists In Python — Part 1 MCQs with Explanations

Code: my_list = [1, 2, 3] print(my_list[1]) Step-by-Step Explanation: 1. List Creation: The code creates a list named my_list with elements [1, 2, 3] . A list in Python is an ordered collection of elements, where each element has an index . The list my_list is indexed as follows: Index 0: 1 Index 1: 2 Index 2: 3 2. Accessing an Element: The code my_list[1] is used to access the element at index 1 in the list. Since Python uses zero-based indexing , the element at index 1 is 2 . 3. Printing the Element: The print() function outputs the value of my_list[1] , which is 2 , to the console. 4. Correct Output: The result of executing the code is the number 2 . Output: The correct output of the code is 2 . Key Points to Remember: 1. Python lists are zero-indexed . The first element is at index 0, the second at index 1, and so on. 2. Using an index out of range (e.g., my_list[3] for the given list) would result in an IndexError . 3. The code is syntactically correct and does not produce any errors.
