How it works...

Here is the explanation for the code:

• np.linspace(0., 1.0, 16) divides the 0 to 1 range into 16 equal parts, as radii define the number of radii equally spread between 0 and 1, and similarly angles define the number of angles equally spread between 0 and 2*pi (360 degrees).
• np.repeat(angles[..., np.newaxis], n_radii, axis=1), repeats the angles array for each of the radii, creating a 32 x 16 matrix:
  • np.newaxis creates an additional dimension for each of the radii.
  • axis=1 specifies that each new dimension should be added as a column.
• x = (radii*np.cos(angles)).flatten() creates x coordinates in Cartesian coordinate system using polar coordinates.
• y = (radii*np.sin(angles)).flatten() creates x coordinates in the Cartesian ...
