Python Assignement

Programm Assignement 1

# Description: This program is a function which calculates pi per Leibniz

formula,based on the number of values passed to it.

def calculate_pi(n):

    total, sign = 0, 1

    for i in range(n):

        term = 1 / (2 * i + 1)

       total += term * sign

        sign *= -1

    total *= 4

    return total

n = int(input("How many terms: "))

print(calculate_pi(n))

PRogramm Assignement2

# This program is to modify the program for Homewor

k Assignment 1

so that it includes exception

# handling, is

, and allows the user to execute the program

multiple times

# without exiting it.

def calculate_pi(n):

   try:

       total, sign = 0, 1

       for i in range(n):

           term = 1 / (2 * i + 1)

           total += term * sign

           sign *= -1

       total *= 4

       return total

   except Exception as e:

       print("Exception occurred..")

       return 0

choice = "yes"

while(choice=="yes"):

   n = int(input("How many terms: "))

   print(calculate_pi(n))

   choice = input("Want to run it again (yes/no)? "

)

PB

Divide the program for Assignment 2 into two modules: 1. A class module which contains a class based on the Leibniz formula, including a constructor for use with the class, and 2. A program module which creates an instance of the class defined in the class module and uses the class attribute to perform the functionality required in Assignement 2. Be sure to correct any issues found with Assignement 2.

#source code:

class Leibniz:
   def __init__(self):
       self.total=0
          
   def calculate_pi(self,n):
       try:
           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
       except Exception as e:
           print("Exception occurred..")
           return 0
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()
