否則，`/users/{user_id}` 的路徑也會匹配 `/users/me`，並「認為」它收到一個值為 `"me"` 的 `user_id` 參數。

同樣地，你不能重新定義同一路徑操作：

{* ../../docs_src/path_params/tutorial003b_py310.py hl[6,11] *}

因為第一個會被優先使用（路徑先匹配到）。

## 預先定義的值 { #predefined-values }

如果你有一個接收「路徑參數」的「路徑操作」，但你希望可用的「路徑參數」值是預先定義好的，你可以使用標準的 Python <abbr title="Enumeration - 列舉">`Enum`</abbr>。

### 建立 `Enum` 類別 { #create-an-enum-class }

匯入 `Enum` 並建立一個同時繼承自 `str` 與 `Enum` 的子類別。

	// Limits for non zip64 files.
	uint16max = (1 << 16) - 1
	uint32max = (1 << 32) - 1

	// Extra header IDs.
	//
	// IDs 0..31 are reserved for official use by PKWARE.
	// IDs above that range are defined by third-party vendors.
	// Since ZIP lacked high precision timestamps (nor an official specification
	// of the timezone used for the date fields), many competing extra fields

# libraries are language agnostic.

# This shared object is not used unless framework_shared_object=true (set in the
