PYTHON

Create in your source_files directory, create a python file inner_functions_assignment.py. In your test directory, create a unit test file test_inner_functions.py.

In your inner_functions_assignment.py, 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[index_position]
  • perimeter(a_list) -- calculates the perimeter
    • recall accessing items in a list: a_list[index_position]
• The outer function, measurements function will call the area() and the perimeter() inner functions
• 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") if __name__ == '__main__': unittest.main()

• Add necessary statements to allow your function to calculate for a square in perimeter and in area.
  • len(a_list) is helpful to decide if the list has 1 or 2 items.
