Overlaying multiple plots on a figure

The City of Seattle has meters installed along the Fremont Bridge that log bicycle traffic on both the East and West side of the bridge, which runs North and South.

In this exercise, you'll use for loops and matplotlib to explore how the traffic on the East and West sides of the bridge change during the day. Understanding how the two sides of the bridge get used during the morning and evening commute is important for any future development into cycling infrastructure that connects to this high traffic route.

A useful function in Python when writing for loops where you need to keep track of where you are is enumerate().

things = ['first thing', 'second', 'yet another']
for ii, item in enumerate(things):
    print(ii, item)

0 first thing
1 second
2 yet another

Explore the shape of the array weekday_traffic to identify which axes correspond to the side of the bridge and hour of the day, respectively.
Loop over the columns of weekday_traffic, using enumerate() to count the number of iterations.
On each loop, plot the column of weekday_traffic with the corresponding label in sidewalk.
Create the legend and show the plot.
