Diese Informationen werden nützlich sein, wenn Sie über [Virtuelle Umgebungen](virtual-environments.md) lernen.

## Fazit { #conclusion }

Mit diesem Wissen sollten Sie ein grundlegendes Verständnis davon haben, was **Umgebungsvariablen** sind und wie man sie in Python verwendet.

a consequence, all volume mounts in containers are now `rslave` on Linux by default. To make this default work in all Linux environments the entire mount tree should be marked as shareable, e.g. via `mount --make-rshared /`. All Linux distributions that use systemd already have the root directory mounted as rshared and hence they need not do anything. In Linux environments without systemd we recommend running `mount --make-rshared /` during boot before docker is started, ([@jsafrane](https://github.com/jsafrane))...

Essas informações serão úteis ao aprender sobre [Ambientes Virtuais](virtual-environments.md).

## Conclusão { #conclusion }

Com isso, você deve ter uma compreensão básica do que são **variáveis ​​de ambiente** e como usá-las em Python.

## Using `TestClient` { #using-testclient }

/// info

To use `TestClient`, first install [`httpx`](https://www.python-httpx.org).

Make sure you create a [virtual environment](../virtual-environments.md), activate it, and then install it, for example:

```console
$ pip install httpx
```

///

Import `TestClient`.

Create a `TestClient` by passing your **FastAPI** application to it.

## Conclusión { #conclusion }

Con esto deberías tener una comprensión básica de qué son las **variables de entorno** y cómo usarlas en Python.

* Fix system container detection in kubelet on systemd. ([#26586](https://github.com/kubernetes/kubernetes/pull/26586), [@derekwaynecarr](https://github.com/derekwaynecarr))
    * This fixed environments where CPU and Memory Accounting were not enabled on the unit that launched the kubelet or docker from reporting the root cgroup when monitoring usage stats for those components.

이 정보는 [가상 환경](virtual-environments.md) 에 대해 알아볼 때 유용할 것입니다.

## 결론 { #conclusion }

이 문서를 통해 **환경 변수**가 무엇이고 파이썬에서 어떻게 사용하는지 기본적으로 이해하셨을 겁니다.

또한 [환경 변수에 대한 위키피디아](https://en.wikipedia.org/wiki/Environment_variable)에서 이에 대해 자세히 알아볼 수 있습니다.
