### Schritt 2: Erzeugen einer `FastAPI`-„Instanz“ { #step-2-create-a-fastapi-instance }

{* ../../docs_src/first_steps/tutorial001_py310.py hl[3] *}

In diesem Beispiel ist die Variable `app` eine „Instanz“ der Klasse `FastAPI`.

Dies wird der Hauptinteraktionspunkt für die Erstellung all Ihrer APIs sein.

### Schritt 3: Erstellen einer *Pfadoperation* { #step-3-create-a-path-operation }

	for metricName, mv := range m.values {
		desc := m.descriptors[metricName]
		promDesc := desc.toPromDesc(namePrefix, extraLabels)

			// labelValues is in the same order as the variable labels in the
			// descriptor.
			labelValues := make([]string, 0, len(v.Labels))
			for _, k := range desc.VariableLabels {
				labelValues = append(labelValues, v.Labels[k])
			}
			metrics = append(metrics,

（FastAPI を使わない場合でも）Python の型の使い方を 2 分で復習したい場合は、短いチュートリアル [Python の型](python-types.md) を参照してください。

型を使った標準的な Python を記述します:

```Python
from datetime import date

from pydantic import BaseModel

# Declare a variable as a str
# and get editor support inside the function
def main(user_id: str):
    return user_id


# A Pydantic model
class User(BaseModel):
    id: int
    name: str
    joined: date
```

$ python main.py

// As we didn't set the env var, we get the default value

Hello World from Python

// But if we create an environment variable first
$ export MY_NAME="Wade Wilson"

// And then call the program again
$ python main.py

// Now it can read the environment variable

Hello Wade Wilson from Python
```
