# Module: `utils.dir2`

A fancy version of Python’s builtin `dir()` function.

## 3 Functions

`IPython.utils.dir2.` `safe_hasattr`(obj, attr)

  In recent versions of Python, hasattr() only catches AttributeError. This catches all errors.

`IPython.utils.dir2.` `get_class_members`(cls)

`IPython.utils.dir2.` `dir2`(obj) → list of strings

  Extended version of the Python builtin dir(), which does a few extra checks, and supports common objects with unusual internals that confuse dir(), such as Traits and PyCrust.

  This version is guaranteed to return only a list of true strings, whereas dir() returns anything that objects inject into themselves, even if they are later not really valid for attribute access (many extension libraries have such bugs).
