Value of y by age class

1. Convert your conditional statement from the last exercise into a function called get_y, that takes age_class as an argument and returns y.

2. Call the function you just created 5 times, once with each of the following values for age_class, and print the values of y:

   • “sapling”,
   • “seedling”,
   • “adult”,
   • “mature”,
   • “established”.
