Tire size constraints

In this lesson, you're going to build on top of the work you've been doing with the ride_sharing DataFrame. You'll be working with the tire_sizes column which contains data on each bike's tire size.

Bicycle tire sizes could be either 26″, 27″ or 29″ and are here correctly stored as a categorical value. In an effort to cut maintenance costs, the ride sharing provider decided to set the maximum tire size to be 27″.

In this exercise, you will make sure the tire_sizes column has the correct range by first converting it to an integer, then setting and testing the new upper limit of 27″ for tire sizes.

Instructions
100 XP
  • Convert the tire_sizes column from category to 'int'.
  • Use .loc[] to set all values of tire_sizes above 27 to 27.
  • Reconvert back tire_sizes to 'category' from int.
  • Print the description of the tire_sizes.
