# Python Program to Make a Simple Calculator

###### Tutorialsrack 22/04/2020 Python

In this Python program, we will learn how to make a simple calculator by which we can perform basic arithmetic operations such as addition, subtraction, multiplication, and division. In this program, we will use `if...elif….else` statement to perform these basic arithmetic operations.

Here is the code of the program to perform basic arithmetic operations.

##### Python Program to Make a Simple Calculator
``````# Python Program to Make a Simple Calculator

# Define a function to adds two numbers
return x + y

# Define a function to subtracts two numbers
def subtract(x, y):
return x - y

# Define a function to multiplies two numbers
def multiply(x, y):
return x * y

# Define a function to divides two numbers
def divide(x, y):
return x / y

print("Select operation.")
print("2.Subtract")
print("3.Multiply")
print("4.Divide")

# Take input from the user
option = input("Choose Option(1/2/3/4): ")

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

if option == '1':

elif option == '2':
print(num1,"-",num2,"=", subtract(num1,num2))

elif option == '3':
print(num1,"*",num2,"=", multiply(num1,num2))

elif option == '4':
print(num1,"/",num2,"=", divide(num1,num2))
else:
print("You choose the Invalid Option!!")
``````
##### Output

Select operation.

2.Subtract

3.Multiply

4.Divide

Choose Option(1/2/3/4): 1

Enter the First Number: 23

Enter the Second Number: 17

23.0 + 17.0 = 40.0
