    You can create a simple Python calculator to perform addition (+), subtraction (-), multiplication (*), division (/), modulus (%), and floor division (//) using basic functions and conditional logic. This approach keeps the code clean, modular, and easy to extend.

    Steps to Implement

    1. Define Functions Create separate functions for each arithmetic operation.

    2. Take User Input Ask the user for two numbers and the desired operation.

    3. Perform Calculation Use conditional statements to call the correct function based on the chosen operator.

    4. Display Result Print the output in a readable format.

    Example Code

    # Define arithmetic operation functions
    def add(x, y):
    return x + y

    def subtract(x, y):
    return x - y

    def multiply(x, y):
    return x * y

    def divide(x, y):
    return "Error: Division by zero" if y == 0 else x / y

    def modulus(x, y):
    return "Error: Division by zero" if y == 0 else x % y

    def floor_divide(x, y):
    return "Error: Division by zero" if y == 0 else x // y

    # Mapping operators to functions
    operations = {
    '+': add,
    '-': subtract,
    '*': multiply,
    '/': divide,
    '%': modulus,
    '//': floor_divide
    }

    # User input
    num1 = float(input("Enter first number: "))
    op = input("Enter operation (+, -, *, /, %, //): ")
    num2 = float(input("Enter second number: "))

    # Perform calculation
    if op in operations:
    result = operations[op](num1, num2)
    print(f"Result: {result}")
    else:
    print("Invalid operation")
