What exactly is happening in the get_row = self.create_row(row) part of the create_grid method?

The logic of what exactly is happening is quite confusing in both create_row and the create_grid methods. Can someone explain it a little more simply? Thank you

Hi!

get_row = self.create_row(row) is creating each row in the grid. get_row is a variable that is holding the result of calling the create_row() method and passing in a certain row number. This is then placed inside of a loop so you can get each row in the grid, because each time the loop runs, row is a new number being passed into the create_row() method.

create_grid() is creating the structure of the grid, including the header, spaces, and pipes |. It uses the create_row() method to get each row and then organizes it using the spaces and pipes for printing to the console so the grid looks nice and neat.

Let me know if this helps or if you have any more questions :)

Thanks a ton! For some reason I was having a hard time wrapping my head around that one.

I think it's a bit confusing because you have two variables named row. One that holds the number in the range function and another that holds the list called row referenced in the create_row method That got me as well at first.
