Counting events before and after noon

In this chapter, you will be working with a list of all bike trips for one Capital Bikeshare bike, W20529, from October 1, 2017 to December 31, 2017. This list has been loaded as onebike_datetimes.

Each element of the list is a dictionary with two entries: start is a datetime object corresponding to the start of a trip (when a bike is removed from the dock) and end is a datetime object corresponding to the end of a trip (when a bike is put back into a dock).

You can use this data set to understand better how this bike was used. Did more trips start before noon or after noon?
