I need guidance

I'm currently in college about to enter my final year and honestly I feel I don't know much. I want to become a full stack software engineer and I'm not sure which programming language is necessary to learn or what to learn. I'm familiar with some languages like python, c++, html, css, JavaScript, java. I'm very good at python and I've used some libraries to build some small projects of mine. I need to know what languages or frameworks I need to learn.
