### 查看文件 { #check-the-docs }

因為「路徑參數」的可用值是預先定義的，互動式文件可以很漂亮地顯示它們：

<img src="/img/tutorial/path-params/image03.png">

### 使用 Python「列舉」 { #working-with-python-enumerations }

「路徑參數」的值會是一個「列舉成員」。

#### 比較「列舉成員」 { #compare-enumeration-members }

你可以把它與你建立的列舉 `ModelName` 中的「列舉成員」比較：

{* ../../docs_src/path_params/tutorial005_py310.py hl[17] *}

 * <p>Thread Safety: This class is thread-safe. Each cached entry holds its own
 * GroovyClassLoader. The cache uses Guava Cache with segment-based locking for
 * lock-free concurrent reads. Each evaluate() call creates a new Script instance
 * to ensure thread isolation of bindings.</p>
 *
 * <p>Note on class-level isolation: Compiled Script classes are cached and reused.

Create a PasswordHash instance with recommended settings - it will be used for hashing and verifying passwords.

/// tip

pwdlib also supports the bcrypt hashing algorithm but does not include legacy algorithms - for working with outdated hashes, it is recommended to use the passlib library.
