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
# Define a function to adds two numbers
def add(x, y):
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("1.Add")
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':
print(num1,"+",num2,"=", add(num1,num2))
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!!")
Select operation.
1.Add
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
