# Python 型別入門 { #python-types-intro }

Python 支援可選用的「型別提示」（也稱為「型別註記」）。

這些「型別提示」或註記是一種特殊語法，用來宣告變數的<dfn title="例如：str、int、float、bool">型別</dfn>。

為你的變數宣告型別後，編輯器與工具就能提供更好的支援。

這裡只是關於 Python 型別提示的快速教學／複習。它只涵蓋使用在 **FastAPI** 時所需的最低限度...其實非常少。

**FastAPI** 完全是以這些型別提示為基礎，並因此帶來許多優勢與好處。

但就算你從不使用 **FastAPI**，學一點型別提示也會有幫助。

/// note | 注意

如果你是 Python 專家，而且已經完全了解型別提示，可以直接跳到下一章。
