The first line, “if tasks:” asks Python to check if the tasks list is empty. If it isn’t, we’ll loop through it using a for loop. For loops have a defined starting and ending point.

Perhaps not. Consider [Tushar Sadhwani] who wanted to create a classic C-style for loop inside of Python. He did it, and the journey is perhaps more interesting than the result.
