Up to this point, with all the tutorials in the docs, you have probably been running a **server program**, for example, using the `fastapi` command, that runs Uvicorn, running a **single process**.

## Ihr Programm ausführen { #run-your-program }

Nachdem Sie die virtuelle Umgebung aktiviert haben, können Sie Ihr Programm ausführen, und es wird das Python innerhalb Ihrer virtuellen Umgebung mit den Paketen verwenden, die Sie dort installiert haben.

<div class="termy">

```console

For example, if you have a function:

```Python
@lru_cache
def say_hi(name: str, salutation: str = "Ms."):
    return f"Hello {salutation} {name}"
```

your program could execute like this:

```mermaid
sequenceDiagram

participant code as Code
participant function as say_hi()
participant execute as Execute function

    rect rgba(0, 255, 0, .1)
