Combining groupby() and resample()

A very powerful method in Pandas is .groupby(). Whereas .resample() groups rows by some time or date information, .groupby() groups rows based on the values in one or more columns. For example, rides.groupby('Member type').size() would tell us how many rides there were by member type in our entire DataFrame.

.resample() can be called after .groupby(). For example, how long was the median ride by month, and by Membership type?
