                print "The perimeter of the rectangle is", rectangle_perimeter, "cm."
            Output:

                $ python example02_int.py
                Let there be a rectangle with the sides of lengths: 10 and 5 cm.
                Then the area of the rectangle is 50 cm squared.
                The perimeter of the rectangle is 30 cm.



            Float

            The float data type can also hold non-integer rational values.
            Input:

                # source_code/appendix_c_python/example03_float.py
                pi = 3.14159
                circle_radius = 10.2
                circle_perimeter = 2 * pi * circle_radius
                circle_area = pi * circle_radius * circle_radius
                print "Let there be a circle with the radius", circle_radius, "cm."
                print "Then the perimeter of the circle is", circle_perimeter, "cm."
                print "The area of the circle is", circle_area, "cm squared."
            Output:

                $ python example03_float.py
                Let there be a circle with the radius 10.2 cm.
                Then the perimeter of the circle is 64.088436 cm.
                The area of the circle is 326.8510236 cm squared.


            String

            A string variable can be used to store text.

            Input:

                # source_code/appendix_c_python/example04_string.py
                first_name = "Satoshi"
                last_name = "Nakamoto"
                full_name = first_name + " " + last_name
                print "The inventor of Bitcoin is", full_name, "."
