Python Program for Calculator

 1) Write a Python Program For Calculator ?

Ans: Suggestion: Here I've given two codes in which first code is simple and 2nd code is little bit complex. but According to me, it will be good if u chooses 2nd code.

1st Program:

Code:

#Program for calculator:

a=int(input("Enter the first number:"))

b=int(input("Enter the Second number:"))

op=input("Enter Operator:")

result=0

if op=='+':

    result=a+b

elif op=='-':

    result=a-b

elif op=='*':

    result=a*b

elif op=='/':

    result=a/b

else:

    print("U Entered unknown operator:")

print(a,op,b,'=',result)

                                                                                Or

2nd Program:

Code:

#2nd Program for calculator:

import sys

def add():

    print("Addition:",a+b)

def sub():

    print("subtraction:",a-b)

def multiply():

    print("Multiplication:",a*b)

def divide():

    print("Divide:",a/b)

while True:

   print("1:Addition,\n2:subtraction,\n3:Multiplication,\n4:Division,\n5:Exit")

    ch=int(input("Enter the following question to perfom operations:"))

    a=int(input("Enter the number:"))

    b=int(input("Enter the 2nd number:"))

  

    if ch==1:

        add()

    elif ch==2:

        sub()

    elif ch==3:

        multiply()

    elif ch==4:

        divide()

    elif ch==5:

        sys.exit()

    else:

        print('\n******Invalid choice')

        print()

Output:
