# For - Else

循环是任何语言的一个必备要素。同样地，`for` 循环就是 Python 的一个重要组成部分。然而还有一些东西是初学者并不知道的。我们将一个个讨论一下。

我们先从已经知道的开始。我们知道可以像这样使用 `for` 循环：

```python
fruits = ['apple', 'banana', 'mango']
for fruit in fruits:
    print(fruit.capitalize())

# Output: Apple
#         Banana
#         Mango
```

这是一个 `for` 循环非常基础的结构。现在我们继续看看，Python 的 `for` 循环的一些鲜为人所知的特性。

## Querying This Documentation
If you need additional information that is not directly available in this page, you can query the documentation dynamically by asking a question.

Perform an HTTP GET request on the current page URL with the `ask` query parameter, and the optional `goal` query parameter:

```
GET https://eastlakeside.gitbook.io/interpy-zh/for_else.md?ask=<question>&goal=<endgoal>
```

`ask` is the immediate question: it should be specific, self-contained, and written in natural language.
`goal` is optional and describes the broader end goal you are ultimately trying to accomplish on behalf of the user. GitBook uses it to tailor the answer towards what is most useful for that goal.

The response will contain a direct answer to the question and relevant excerpts and sources from the documentation.

Use this mechanism when the answer is not explicitly present in the current page, you need clarification or additional context, or you want to retrieve related documentation sections.
