Python Exercises - How to build a basic calculator | Method #1 | Python Exercise #2

Here, we will create a Calculator in Python using if else as decision conditions.

It will be a good exercise to get us started with Python in practice.

Open your text editor and create a new Python file.

The calculator we are going to create will perform only 4 operations, which will be addition, subtraction, multiplication and division.

Code

#Menu

Print("Enter:\n\n1.Addition\n2.Subtraction\n3.Multiplication\n4.Division\n")  

 

# Menu

print("Enter:\n\n1.Addition\n2.Subtraction\n3.Multiplication\n4.Division\n")  

 

choice = input("Enter choice: ")  

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

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

 

if choice == '1':  

   print(a + b)  

 

elif choice == '2':  

   print(a - b)  

 

elif choice == '3':  

   print(a * b)

   

elif choice == '4':  

   print(a / b)  

   

else:  

   print("Invalid choice")
