"""
Details : AutoBard-Coder is code genrator for bard. It is used to generate code from bard response.
its using Bard API to interact with bard and refine the results for coding purpose.
The main purpose of this is for research and educational purpose.
This is using unofficial bard api and not affiliated with bard in any way - So use it at your own risk.
This can generate the code from prompt and fix itself unless the code is fixed.
Language : Python
Dependencies : streamlit, bard-coder
