Python Script for Database Caching

# Tasks

1. Creating a python script to work with Serial port.
- Find a pip package similar to npm SerialPort
- Make a pip freeze requirements.txt for containerization
- For Development: virtual python environment
2. Create python code that works with Redis
- Find a pip package to work with a redis data base
- Make a pip freeze requirements.txt for containerization
- Write information that is time stamped
3. Convert a string Json object to a dictionary in python.
- Find a pip package to work with Json objects via a string
- Make a pip freeze requirements.txt for containerization
4. Put all the code in one script file for testing.

No target file or test is named; start by reviewing the repository's existing TypeScript/Express structure and deciding where the single Python test script and requirements.txt belong. Done means the script covers serial-port access, Redis writes with timestamps, string-to-dictionary JSON conversion, and the listed environment/containerization requirements.
