Add tasks with add_task.
Adding tasks (add_task)
Our empty list is ready. Now we write an add_task function to add tasks. The function takes a title and appends it to the list:
def add_task(title):
tasks.append(title)The function reads the tasks list from outside; because the list is at module level. Each call adds a new task to the list.
Calling the function
Let us call our defined function to add tasks:
add_task("Buy bread")
add_task("Buy milk")Each call adds a new task to the list. The function can use the tasks list from outside because Python functions can access module-level variables.
This approach is common in small scripts; in bigger projects a class structure is preferred.
Practice Add the add_task function
Define a function called add_task that takes a title parameter and does tasks.append(title) in the body. Add two tasks with add_task("Buy bread") and add_task("Buy milk"). Then print print(tasks).
