Signed up for Chatgpt Plus when instead I think i should have signed up for OpenAI Codex?

I’m just starting some coding and few other classes at community College and I love using the paid version of chatgpt, with one exception. I would like to be able to ask Chatgpt a python query but the more advanced I get into python, the more incorrect answers chatgpt is giving me.Its getting to be where the MAJORITY of query answers are wrong!
Is there a better alternative to chatgpt that could possibly give me more precise and correct answers when asking python queries? I read about something called Playground and/or openai codex. if those are better at that Id much prefer to spend my money there! Please advise!
