An even better way would be to think about the steps necessary to do this and then writing them down in pseudo-code. After that you can look up the functions/tools that will help you accomplish this task. One of the most important skills a programmer can have is called 'algorithmic thinking'. That is, essentially, the ability to break a problem down into smaller pieces in order to eventually solve it. So, think about this: What steps do you need to take to turn this csv file into a Python dictionary object? Imagine that you were going to do this by hand. How would you do it?
