Making NumPy arrays from lists

Recall how lists can contain anything? They can even contain other lists. In this exercise, you're going to demonstrate this feature and show how useful it is for creating our own NumPy arrays.

Seven lists are loaded into your workspace, each named after a day of the week: monday, tuesday, and so on. Each list contains the average hourly bicycle traffic across the Fremont bridge.
