On the other side, there are thousands of users in the chat systems, so there's a high chance you'll find someone to talk to there, almost all the time. 😄

Then the next concepts to consider are all about the program running your actual API (e.g. Uvicorn).

## Program and Process

We will talk a lot about the running "**process**", so it's useful to have clarity about what it means, and what's the difference with the word "**program**".

### What is a Program

In Python 3.10 is er ook een **nieuwe syntax** waarin je de mogelijke types kunt scheiden door een <abbr title='ook wel "bitwise of operator" genoemd, maar die betekenis is hier niet relevant'>verticale balk (`|`)</abbr>.
