# Task: Create a Calculator

# Your task is to create a basic calculator program using Python.

# The program should allow the user to perform simple arithmetic operations on two numbers.

# Requirements:

# Prompt the user to enter two numbers.
# Prompt the user to select an operation from the following options:
# addition
# subtraction
# multiplication
# division.

# Based on the selected operation, perform the corresponding calculation. Display the result to the user.

# Note:

# Ensure that the program handles division by zero and provides an appropriate error message if the user attempts to divide by zero.
# Consider using functions to encapsulate the calculation logic for each operation.
# Include clear instructions and error handling for invalid input.


print("Welcome to the Calculator Program!")
