Create in your source _files directory, create a python file In your test directory, create a unit test file
In your, write a function measurements that accepts a list of measurements for a rectangle and returns a string with perimeter and area

-Write 2 inner functions that accept a list as parameter:
area(a_list) -- calculates the area
-Recall accessing items in a list: a_list[#]
perimeter(a_list) -- calculates the perimeter
-Recall accessing items in a list: a_list[#]

-The outer, measurements function will call the area() and the perimeter()
-The outer function will build a string and return the following string:
Perimeter = 11.0 Area = 7.14 #if this is the perimeter and the area.

Test your code with the unit test below, and notice only the first test will pass.

class MyTestCase(unittest.TestCase):
def test_measurements_rectangle(self):
self.assertEqual(measurements([2.1, 3.4]), "Perimeter = 11.0 Area = 7.14")
def test_measurements_square(self):
self.assertEqual(measurements[3.5]), "Perimeter = 14.0 Area = 12.25")
