Selective import

General imports, like import math, make all functionality from the math package available to you. However, if you decide to only use a specific part of a package, you can always make your import more selective:

from math import pi

Let's say the Moon's orbit around planet Earth is a perfect circle, with a radius r (in km) that is defined in the script.

Instructions
100 XP
  • Perform a selective import from the math package where you only import the radians function.
  • Calculate the distance travelled by the Moon over 12 degrees of its orbit. Assign the result to dist. You can calculate this as r * phi, where r is the radius and phi is the angle in radians. To convert an angle in degrees to an angle in radians, use the radians() function, which you just imported.
  • Print out dist.
