Description

Implement the hue_ring method with parameters for the outer_radius and the inner_radius of the ring, to recreate the following graphic.

The graphic is composed of 360 circular sectors appropriately rotated and colored. The color of each sector has a different hue (from 0 to 359), is fully saturated (saturation of 1.0) and fully light (value of 1.0), to achieve this you can use the pytamaro hsv_color function and the circular_sector function.

Note: in this activity we assume that you know how to use a for-loop. If you don't, try to do our hue-bar activity first, where we guide you a little bit through the implementation of a for-loop, and then come back when you are ready!

The hue_to_sector function

Let's now implement a hue_to_sector function to map from a hue to a sector.

This function should return a sector of the given radius with ideally angle of 1°, but for approximation reasons we suggest that you use an angle of 2°. The color of the sector depends on the value of the hue parameter: assert that it's a valid number from 0 to 360.

The hue_ring function

This function takes the wanted outer_radius and inner_radius of the ring.

It produces 360 hue sectors corresponding to each hue value from 0 to 359, all pinned in the bottom left and rotated of 1° with respect to one another. Then it returns a Graphic with each sector composed together with the others. Ultimately, it should overlay a white inner circle on the final colored ring.

Use the pytamaro pin, compose, rotate and overlay functions.

You can use the pytamaro empty_graphic function.

To achieve this you can use a for-loop. In each step of the loop you want to create a sector of a different hue, pin it in the bottom left, rotate it accordingly and compose it together with the previous sectors.
