How to create calculator in Python using If and Else

Here, we will create a Calculator in Python using if else as decision conditions. It will be a good exercise to get us started using 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.

 

# 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")  

 

Output:

 

Enter:

1.Addition
2.Subtraction
3.Multiplication
4.Division

Enter choice: 2
Enter the first number: 3
Enter the second number: 2
