Kata

Description:

In this task, you need to implement a function add_task that adds a new task to a list of tasks. The function should accept a task and an optional list of tasks. If the list is not provided, the function should create a new list. The goal is to demonstrate why using mutable objects (like lists) as default arguments is a bad idea and how to fix it.

Initial Function Signature:

def add_task(task, task_list=[]) -> list:
    # Fix it

Example:

tasks = add_task("Buy milk")
print(tasks)  # Expected output: ['Buy milk']

tasks = add_task("Buy bread")
print(tasks)  # Expected output: ['Buy bread']

tasks = add_task("Buy eggs", [])
print(tasks)  # Expected output: ['Buy eggs']

Hint:

• Avoid using mutable objects as default arguments to prevent unexpected behavior.
