#### Operacje

"Operacje" tutaj odnoszą się do jednej z "metod" HTTP.

Jedna z:

* `POST`
* `GET`
* `PUT`
* `DELETE`

...i te bardziej egzotyczne:

* `OPTIONS`
* `HEAD`
* `PATCH`
* `TRACE`

W protokole HTTP można komunikować się z każdą ścieżką za pomocą jednej (lub więcej) "metod".

---

Podczas tworzenia API zwykle używasz tych metod HTTP do wykonania określonej akcji.

## Read env vars in Python

You could also create environment variables **outside** of Python, in the terminal (or with any other method), and then **read them in Python**.

For example you could have a file `main.py` with:

```Python hl_lines="3"
import os

name = os.getenv("MY_NAME", "World")
