# 46.3. Sharing Data

全域字典變數 SD 可用於在重複呼叫同一函數之間所儲存的私有資料。全域字典變數 GD 是公用資料，可用於同一個資料庫連線中的所有 Python 函數； 請小心使用。

每個函數在 Python 直譯器中都有其自己的執行環境，因此 myfunc2 不能使用 myfunc 的全域變數和函數參數。如上所述，其例外是 GD 字典變數中的資料。

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

Perform an HTTP GET request on the following URL with the `ask` and `goal` query parameters:

```
GET https://docs.postgresql.tw/15/server-programming/pl-python-python-procedural-language-1/sharing-data.md?ask=<question>&goal=<user_goal>
```

`ask` is the immediate question: it should be specific, self-contained, and written in natural language.
`goal` is what the user is ultimately trying to achieve, the reason they need the answer. Sharing it helps GitBook give you a better, more relevant answer. A goal is most helpful when it describes the outcome the user wants rather than restating the question. For example, with `ask=how do I create an API token`, a goal like `automate deployments from our CI pipeline` lets GitBook tailor the answer to that use case.

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.
