List Methods

Strings are not the only Python types that have methods associated with them. Lists, floats, integers and booleans are also types that come packaged with a bunch of useful methods. In this exercise, you'll be experimenting with:

  • .index(), to get the index of the first element of a list that matches its input and
  • .count(), to get the number of times an element appears in a list.

You'll be working on the list with the area of different parts of a house: areas.

Instructions

  • Use the .index() method to get the index of the element in areas that is equal to 20.0. Print out this index.
  • Call .count() on areas to find out how many times 9.50 appears in the list. Again, simply print out this number.
