A for loop has a header that ends with a colon and an indented body below. A for statement is called a loop because the flow of execution is through the body, and then back up to the header. It works as expected. The code prints the number 1, 2, 3 and then stops. The question now is, how does the loop constructs the work behind the scenes. i.e. How does the loop fetch individual elements from the object it is looping over and know when to stop? The answer to the question is Python's iterator protocol: Apr 06, 2021 · Here, we have taken a traditional approach of iterating over a list i.e using for loop.
