Question

Provide your own examples of the following using Python lists. Create your own examples. Do not copy them from another source.

Nested lists

The "*" operator

List slices

The "+=" operator

A list filter

A list operation that is legal but does the "wrong" thing, not what the programmer expects

Provide the Python code and output for your program and all your examples.

Answer 1

Nested lists, the "*" operator, and list slices in Python.

Step-by-step explanation:

The correct answer is option A. Here are some examples of the requested Python operations:

1. Nested lists: A nested list is a list within another list. For example, if we want to represent a grid of numbers, we can use a nested list like this:

grid = [[1, 2, 3], [4, 5, 6], [7, 8, 9]]

1. The "*" operator: This operator is used to repeat a list. For example:

numbers = [1, 2, 3]
repeated_numbers = numbers * 3
print(repeated_numbers) # Output: [1, 2, 3, 1, 2, 3, 1, 2, 3]

1. List slices: Slicing allows us to extract a sublist from a list. For example:

numbers = [1, 2, 3, 4, 5]
sliced_list = numbers[1:4]
print(sliced_list) # Output: [2, 3, 4]
