The information is sufficient to implement a module browser. The information is extracted from the Python source code rather than by importing the module, so this module is safe to use with untrusted code. This restriction makes it impossible to use this module with modules not implemented in Python, including all standard and optional extension modules. `pyclbr.``readmodule`(*module*, *path=None*)Return a dictionary mapping module-level class names to class descriptors. If possible, descriptors for imported base classes are included. Parameter *module* is a string with the name of the module to read; it may be the name of a module within a package. If given, *path* is a sequence of directory paths prepended to `sys.path`, which is used to locate the module source code. `pyclbr.``readmodule_ex`(*module*, *path=None*)Return a dictionary-based tree containing a function or class descriptors for each function and class defined in the module with a `def` or `class` statement. The returned dictionary maps module-level function and class names to their descriptors. Nested objects are entered into the children dictionary of their parent. As with readmodule, *module* names the module to be read and *path* is prepended to sys.path. If the module being read is a package, the returned dictionary has a key `'__path__'` whose value is a list containing the package search path. 3\.7 新版功能: Descriptors for nested definitions. They are accessed through the new children attribute. Each has a new parent attribute. The descriptors returned by these functions are instances of Function and Class classes. Users are not expected to create instances of these classes. ## 函數對象 Class `Function` instances describe functions defined by def statements. They have the following attributes: `Function.``file`Name of the file in which the function is defined. `Function.``module`The name of the module defining the function described. `Function.``name`The name of the function. `Function.``lineno`The line number in the file where the definition starts. `Function.``parent`For top-level functions, None. For nested functions, the parent. 3\.7 新版功能. `Function.``children`A dictionary mapping names to descriptors for nested functions and classes. 3\.7 新版功能. ## 類對象 Class `Class` instances describe classes defined by class statements. They have the same attributes as Functions and two more. `Class.``file`Name of the file in which the class is defined. `Class.``module`The name of the module defining the class described. `Class.``name`The name of the class. `Class.``lineno`The line number in the file where the definition starts. `Class.``parent`For top-level classes, None. For nested classes, the parent. 3\.7 新版功能. `Class.``children`A dictionary mapping names to descriptors for nested functions and classes. 3\.7 新版功能. `Class.``super`A list of `Class` objects which describe the immediate base classes of the class being described. Classes which are named as superclasses but which are not discoverable by [`readmodule_ex()`](#pyclbr.readmodule_ex "pyclbr.readmodule_ex")are listed as a string with the class name instead of as `Class` objects. `Class.``methods`A dictionary mapping method names to line numbers. This can be derived from the newer children dictionary, but remains for back-compatibility. ### 導航 - [索引](../genindex.xhtml "總目錄") - [模塊](../py-modindex.xhtml "Python 模塊索引") | - [下一頁](py_compile.xhtml "py_compile --- Compile Python source files") | - [上一頁](tabnanny.xhtml "tabnanny --- 模糊縮進檢測") | -  - [Python](https://www.python.org/) ? - zh\_CN 3.7.3 [文檔](../index.xhtml) ? - [Python 標準庫](index.xhtml) ? - [Python 語言服務](language.xhtml) ? - $('.inline-search').show(0); | ?
