1. Add methods which do calculations based on the pi attribute to the class which you wrote above.

2. Modify your program module so that it demonstrates those new class methods. Be sure to correct any issues found with Homework 3

Answer 1

class Leibniz:
    def __init__(self):
        self.total = 0

    def calculate_pi(self, n):
        self.total, sign = 0, 1
        for i in range(n):
            term = 1 / (2 * i + 1)
            self.total += term * sign
            sign *= -1
        self.total *= 4
        return self.total


class Main_Calc:
    choice = "yes"
    while choice != "no":
        try:
            n = int(input("How many terms: "))
            Object_pi = Leibniz()
            print(Object_pi.calculate_pi(n))
            choice = input("Want to run it again (yes/no)? ")
        except:
            print("Enter the Integer")


if __name__ == "__main__":
    Call_class = Main_Calc()
