In this python program code, we will learn to form a simple calculator which will perform a basic arithmetic operation such as addition, subtraction, multiplication, and division, depending upon the input given by the user.

Here, we have made a function named calc(n) which will further perform the desired operation.

# Algorithm

Define a function named calc(n).
In the function, sum “s” and product “p” initialize to 0 and 1 respectively.
Take two numbers as input from the user, further operations are performed on it.
For different values of i we will perform different operations and it is passed in the function calc().
We perform the different operation on the number which is input by the user .
Exit.

Code:

def calc(n):\n    s=0
\n    p=1
\n    a=int(input(\"first number\"))
\n    b=int(input(\"second number\"))
\n    if n==1:
\n        s=a+b
\n        print(\"sum\",s)
\n    elif n==2:
\n        p=a*b
\n        print(\"prod\",p)
\n    elif n==3:
\n        s=a-b
\n        print(\"diff\",s)
\n    else:
\n        p=a/b
\n        print(\"divide\",p)
\ni=int(input(\"enter for calculation 1. add 2. product 3.subtract 4.divide\"))
\ncalc(i)

Output:

enter for calculation 1. add 2. product 3.subtract 4.divide 2\n2 \n3 \nprod 6 \nenter for calculation 1. add 2. product 3.subtract 4.divide 4 \nfirst number4 \nsecond number2 \n
