Sample Solution:-

Python Code:

import fractions

f1 = fractions.Fraction(2, 3)
f2 = fractions.Fraction(3, 7)

print('{} + {} = {}'.format(f1, f2, f1 + f2))
print('{} - {} = {}'.format(f1, f2, f1 - f2))
print('{} * {} = {}'.format(f1, f2, f1 * f2))
print('{} / {} = {}'.format(f1, f2, f1 / f2))

Sample Output:

2/3 + 3/7 = 23/21                                                                                             
2/3 - 3/7 = 5/21                                                                                              
2/3 * 3/7 = 2/7                                                                                               
2/3 / 3/7 = 14/9

In this tutorial, we will write a Python program to add, subtract, multiply and divide two input numbers.

Program to perform addition, subtraction, multiplication and division on two input numbers in Python

In this program, user is asked to input two numbers and the operator (+ for addition, – for subtraction, * for multiplication and / for division). Based on the input, program computes the result and displays it as output.
To understand this program you should know how to get the input from user and the basics of if..elif..else statement.

# Program published on https://beginnersbook.com

# Python program to perform Addition Subtraction Multiplication
# and Division of two numbers

num1 = int(input("Enter First Number: "))
num2 = int(input("Enter Second Number: "))

print("Enter which operation would you like to perform?")
ch = input("Enter any of these char for specific operation +,-,*,/: ")

result = 0
if ch == '+':
    result = num1 + num2
elif ch == '-':
    result = num1 - num2
elif ch == '*':
    result = num1 * num2
elif ch == '/':
    result = num1 / num2
else:
    print("Input character is not recognized!")

print(num1, ch , num2, ":", result)

Output 1: Addition

Enter First Number: 100
Enter Second Number: 5
Enter which operation would you like to perform?
Enter any of these char for specific operation +,-,*,/: +
100 + 5 : 105

Output 2: Division

Enter First Number: 20
Enter Second Number: 5
Enter which operation would you like to perform?
Enter any of these char for specific operation +,-,*,/: /
20 / 5 : 4.0

Output 3: Subtraction

Enter First Number: 8
Enter Second Number: 7
Enter which operation would you like to perform?
Enter any of these char for specific operation +,-,*,/: -
8 - 7 : 1

Output 4: Multiplication

Enter First Number: 6
Enter Second Number: 8
Enter which operation would you like to perform?
Enter any of these char for specific operation +,-,*,/: *
6 * 8 : 48

Doing fractions or math using Python is not something new, but I was anxious to try it out because my kids have been learning fractions in school. So I wanted to be that super dad who can solve the fractions very quickly or at least I could use it to verify their homework.

Here are samples that you can copy and paste into your text editor and try out without needing to do any modifications. These examples are tested in Python 2.7.13 in Mac OS.

Here are some basic examples setting fractions and doing some basic operations. There is also exception handling for zero division:

__author__ = 'Almir Mustafic'
from fractions import Fraction
"""

def main():
    print("main program")
    set_fractions()
    fraction_operations()
    input_and_calculate_fractions()
def set_fractions():
    print("set_fractions method ..............")



 f1 = Fraction(3, 4)
 print(f1)
 f2 = Fraction(8, 4)
 print(f2)
def fraction_operations():
 print("fraction_operations method ............. ")
 fsum = Fraction(3, 4) + Fraction(6, 4)
 print(fsum)
 my_float = float(fsum)
 print(my_float)
def input_and_calculate_fractions():
 print("input_and_calculate_fractions method ..............")
 # Enter for example: 2/3
 # Try entering 2/0 to see how it tells you that it is invalid
 try:
 a = Fraction(raw_input("enter a fraction: "))
 print(a)
 print(float(a))
 except ZeroDivisionError:
 print("Invalid fraction")

Here is a more complete example that allows you to interact with it. You can perform add, subtract, multiply and divide.

__author__ = 'Almir Mustafic'
from fractions import Fraction
def main():
    print("main program")
    perform_fraction_operations()
def perform_fraction_operations():
    while True:
        try:
            print("========================================================")
            fraction01 = Fraction(raw_input('Enter fraction: '))
            fraction02 = Fraction(raw_input('Enter another fraction: '))
            my_operation = raw_input('Perform one the following operations: Add (A), Subtract (S), Divide (D), Multiply (M) : ')



 print("________________________________________________________")
 if my_operation.capitalize() == 'ADD' or my_operation.capitalize() == "A":
 add(fraction01, fraction02)
 if my_operation.capitalize() == 'SUBTRACT' or my_operation.capitalize() == "S":
 subtract(fraction01, fraction02)
 if my_operation.capitalize() == 'DIVIDE' or my_operation.capitalize() == "D":
 divide(fraction01, fraction02)
 if my_operation.capitalize() == 'MULTIPLY' or my_operation.capitalize() == "M":
 multiply(fraction01, fraction02)
 except ValueError:
 print('Invalid fraction entered')
 except ZeroDivisionError:
 print("Zero division fraction. Do NOT do this :)")
 print("========================================================")
 answer = raw_input('Do you want to exit? (yes) for yes or just press enter to continue: ')
 if answer == 'yes' or answer == 'y':
 break
def add
(f1, f2):
 print('Result of adding {0} and {1} is {2} '.format(f1, f2, f1+f2))
def subtract(f1, f2):
 print('Result of subtracting {1} from {0} is {2}'.format(f1, f2, f1-f2))
def divide(f1, f2):
 print('Result of dividing {0} by {1} is {2}'.format(f1, f2, f1/f2))
