ChatGPT.py is a modified version of simple Python script app.py, from the GitHub repo, which is referred to from the article How to use ChatGPT with Python, to explore features of openai ChatGPT on Android 11 (API level 30) using the Pydroid 3 IDE for Python 3.9 and save the conversation to chatlog.txt, in the same directory.
pandas and openai must be installed, if they aren't, then:
pip install pandas
pip install openai
If you don't have an openai account sign up for one and then generate an API key and replace OPEN_API_KEY, on line number 3 of ChatGPT.py with the API key you were given. Save and then run.
