What does enumerate do here?
There was a problem hiding this comment.
So in this line it looks like the enumerate function searches a row in the shape array. This might look like ['..00..'].
As it looks at each element, if it sees a 0, it will fill that space in with a rectangle piece. If there is a ., it will continue to the next iteration. In this way one row of the shape can be drawn. Doing this over all of the rows will cause a shape to take form. The enumerate function is a convenient way to track the index of an item in an array while cycling through it. Here is a video example explaining the function. https://www.youtube.com/watch?v=-MZiQaNI0QA

Hey. I just did the tetris tutorial and it was great. I found a way to add a line of code which will add gridlines to the waiting piece.
