There are several full length programs in the book. I would like you to copy these pieces of code and get them to run. Your code must have the following template:
def main(): # the body of the program ... main()Each program will be in a file by itself with .py extension. You must make sure that it runs as shown in the book. These programs do NOT have to be turned in. However, you are likely to see variations of these programs in the quizzes.
Correct formula for Listing 3.2:
A = acos ((b * b + c * c - a * a) / (2 * b * c)) B = acos ((c * c + a * a - b * b) / (2 * c * a)) C = acos ((a * a + b * b - c * c) / (2 * a * b))
