I saw a similar repl project on the share page using a package called "goslate." This project had a terrible user-interface so I decided to make my own using goslate, google translates python package. Also, I made this just because I was bored out of ideas.
When I actually inspected the package there was so many languajes I could translate with using it. You can even translate to latin! (A very, very old languaje that Ancient Rome used.) So, if your making a python translater I 100% suggest that you use goslate.
There's about 104 languajes you can translate to!
