This information will be useful when learning about [Virtual Environments](virtual-environments.md).

## Conclusion { #conclusion }

With this you should have a basic understanding of what **environment variables** are and how to use them in Python.

And you have to wait 🕙 in the line for a long time or you lose your turn.

You probably wouldn't want to take your crush 😍 with you to run errands at the bank 🏦.

### Burger Conclusion { #burger-conclusion }

In this scenario of "fast food burgers with your crush", as there is a lot of waiting 🕙, it makes a lot more sense to have a concurrent system ⏸🔀⏯.

This is the case for most of the web applications.

  protected B self() {
    return (B) this;
  }

  // Test Data

  private @Nullable G subjectGenerator;
  // Gets run before every test.
  private Runnable setUp;
  // Gets run at the conclusion of every test.
  private Runnable tearDown;

  @CanIgnoreReturnValue
  protected B usingGenerator(G subjectGenerator) {
    this.subjectGenerator = subjectGenerator;
    return self();
  }

  protected B self() {
    return (B) this;
  }

  // Test Data

  private @Nullable G subjectGenerator;
  // Gets run before every test.
  private Runnable setUp;
  // Gets run at the conclusion of every test.
  private Runnable tearDown;

  @CanIgnoreReturnValue
  protected B usingGenerator(G subjectGenerator) {
    this.subjectGenerator = subjectGenerator;
    return self();
  }

這大致等同於輸入以下指令：

<div class="termy">

```console
$ C:\opt\custompython\bin\python
```

</div>

當學習[虛擬環境](virtual-environments.md)時，這些資訊將會很有用。

## 結論 { #conclusion }

透過這個教學，你應該對**環境變數**是什麼以及如何在 Python 中使用它們有了基本的了解。

你也可以在 [環境變數的維基百科條目](https://en.wikipedia.org/wiki/Environment_variable) 中閱讀更多。

在許多情況下，環境變數的用途和適用性可能不會立刻顯現。但是在開發過程中，它們會在許多不同的場景中出現，因此瞭解它們是非常必要的。

모든 은행원이 한 고객씩 순서대로 모든 일을 처리합니다 👨‍💼⏯.

그리고 여러분은 오랫동안 줄에서 기다려야 🕙 하며, 그렇지 않으면 차례를 잃습니다.

아마 은행 🏦 업무를 보러 갈 때 짝사랑 상대 😍 를 데려가고 싶지는 않을 것입니다.

### 햄버거 예시의 결론 { #burger-conclusion }

"짝사랑 상대와의 패스트푸드점 햄버거" 시나리오에서는 기다림 🕙 이 많기 때문에, 동시 시스템 ⏸🔀⏯ 을 사용하는 것이 훨씬 더 합리적입니다.

대부분의 웹 애플리케이션이 그렇습니다.

매우 많은 사용자들이 있고, 서버는 그들의 좋지 않은 연결을 통해 요청이 전송되기를 기다립니다 🕙.

그리고 응답이 돌아오기를 다시 기다립니다 🕙.

Y tienes que esperar 🕙 en la fila por mucho tiempo o pierdes tu turno.

Probablemente no querrías llevar a tu crush 😍 contigo a hacer trámites en el banco 🏦.

### Conclusión de las Hamburguesas { #burger-conclusion }

En este escenario de "hamburguesas de comida rápida con tu crush", como hay mucha espera 🕙, tiene mucho más sentido tener un sistema concurrente ⏸🔀⏯.
