New Python Program: Simple Calculator

Tạo tệp có tên simple_calculator.py dưới dạng một chương trình dòng lệnh Python 3. Trước tiên, hãy xem lại các yêu cầu của tác vụ, sau đó chạy chương trình với các đầu vào ví dụ, từng phép toán số học, đầu vào không hợp lệ và phép chia cho 0. Công việc hoàn tất khi chương trình đưa ra lời nhắc rõ ràng, trả về kết quả chính xác và xử lý lỗi một cách phù hợp.

Hello Python enthusiasts! Let's enhance our repository with a Simple Calculator implemented in Python. This beginner-friendly task involves creating a command-line calculator that can perform basic arithmetic operations. This program will showcase fundamental input handling, arithmetic operations, and conditional statements in Python.

Tasks:

• Implement functions for addition, subtraction, multiplication, and division.
• Allow users to input two numbers and select an operation (+, -, *, /).
• Perform the corresponding operation and display the result to the user.
• Handle division by zero and invalid inputs gracefully.
• Provide clear instructions and error messages for the users.

Guidelines:

• Use Python 3.x for the program.
• Implement functions to handle each arithmetic operation separately.
• Ensure the calculator provides clear prompts and feedback to the user.
• Include comments in your code to explain the logic and functionality.
• Test the calculator with various inputs to ensure accurate calculations.

Example:

Welcome to the Simple Calculator!

Please enter the first number: 10
Please enter the second number: 5
Select operation (+, -, *, /): +

Result: 10 + 5 = 15
