How to rewrite python code from sqlite3 to postgres?

Question

Python

I have a completely ready tg bot running on sqlite3 database. When I wanted to upload it to Heroku, I realized that such a database is not supported there. I tried to find some understandable Postgresql tutorials, but in the end I didn’t succeed. The syntax for sqlite3 and postgresql is the same, so I just need to connect to it somehow correctly. I will not read various documentations and the like, because I do not have time for this and the level of English is not at a good enough level for me to understand something there, besides, the project is small - at the school level. I would be glad if you wrote in a nutshell how to connect to it and a code example. Thank you!
