Introduction:
To build a simple calculator using if and elif efficiently, utilize appropriate control statements. We use ‘if’ and ‘elif’ statements to handle some basic Arithmetic operations like,
Addition,
Subtraction,
Multiplication,
Division
Program:
def calculator(): print("Simple Calculator Using if and elif") print("Select operation do you want:") print("1. Addition (+)") print("2. Subtraction (-)") print("3. Multiplication (*)") print("4. Division (/)") choice = input("Enter your choice: ") if choice in ['1', '2', '3', '4']: n1 = float(input("Enter first number: ")) n2 = float(input("Enter second number: ")) if choice == '1': print(f"Addition of two numbers is {n1 + n2}") elif choice == '2': print(f"Subtraction of two numbers is {n1 - n2}") elif choice == '3': print(f"Multiplication of two numbers is {n1 * n2}") elif choice == '4': if n2 != 0: print(f"Division of two numbers is {n1 / n2}") else: print("Error! Division by zero is not allowed.") else: print("Invalid input. Please enter a number between 1 and 4.") calculator()
Output:
Simple Calculator Using if and elif Select operation do you want: 1. Addition (+) 2. Subtraction (-) 3. Multiplication (*) 4. Division (/) Enter your choice: 1 Enter first number: 2 Enter second number: 5 Addition of two numbers is 7.0 Select operation do you want: 1. Addition (+) 2. Subtraction (-) 3. Multiplication (*) 4. Division (/) Enter your choice: 2 Enter first number: 5 Enter second number: 3 Subtraction of two numbers is 2.0 Select operation do you want: 1. Addition (+) 2. Subtraction (-) 3. Multiplication (*) 4. Division (/) Enter your choice: 3 Enter first number: 3 Enter second number: 6 Multiplication of two numbers is 18.0 Select operation do you want: 1. Addition (+) 2. Subtraction (-) 3. Multiplication (*) 4. Division (/) Enter your choice: 4 Enter first number: 6 Enter second number: 3 Division of two numbers is 2.0
Conclusion:
In the conclusion, Python programming offers compact statements to build a simple calculator using if and elif in Python.
