Answer 1

I suggest breaking this into several smaller steps:

1. Read the CSV file into a 2D list or 2D array.
2. Calculate the averages of each column.

Each of these steps can be implemented as two separate functions. (In a realistic situation where the CSV file is large, reading the complete file into memory might be prohibitive due to space constraints. However, for a learning exercise, this is a great way to gain an understanding of writing your own functions.)
