AkashKhulpe5/Spam_detection ? reverse-engineered prompt

Build me a simple Python app for spam detection.

I want to be able to give it a text message or email content and have it tell me if it looks like spam or not spam, with a clear confidence score if possible. If the project needs sample data, add a small example dataset or a way to plug one in, and make sure the main script runs cleanly from the command line. Keep it easy to understand and include any setup steps that are needed so I can run it locally without guessing.

If there are better current libraries or methods for text classification, use them and look up the latest docs online if needed. Please also make the code readable, handle basic input errors, and leave me with something I can test right away.
