Python version of Langchain integrations.

Experimental approach.

1. Fork the repo
2. Copy .env.example to .env (ignored by Git) and insert your API keys
3. Create a virtual environment and install the requirements
4. To load OPENAI_API_KEY to environmental variables insert this to venv/bin/activate script:

OPENAI_API_KEY=<your key>
export OPENAI_API_KEY

5. Rewrite the code using Python applying the clean code standards. Check 01_langchain_init and 02_langchain_format for reference.
6. Don't remove the original .ts files
7. Create a PR. Commit messages and PR descriptions should indicate what has been done.
