Define a global counter variable for your for loop called total_sum at 0.For the sake of this lesson though? Either way works just fine. To answer your question, using range(len(List)) is probably what you would want to do for more intricate code where you are actually modifying things.

If the console on the site worked I would just try to figure out how it works by trying out different things, but it doesn’t, so I’m just asking here.įigured I’d make it more readable so you know what’s happening. This confuses me a lot and I am most likely just misunderstanding something, but I don’t see where that piece of code does what it is supposed to do. In my understanding that means that the method iterates through a newly generated list that represents the indexes of the list “list” But in the lesson before it said that “the Python range() function is just a shortcut for generating a list”. It says that using this method you iterate through a list using indexes. Here’s the example that is given: for i in range(len(list)): I just don’t understand how the second method is supposed to work.

The first method (“for item in list”) is no problem, went through that long enough. In the lesson two methods are explained on how to iterate through lists. I know I don’t need to know this to get through the lesson, but I’m just trying to understand what is told to me.
