Module: utils.dir2 — IPython 5.1.0 documentation

# 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.` `dir2`(obj) → list of strings

  Extended version of the Python builtin dir(), which does a few extra checks.

  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).

`IPython.utils.dir2.` `get_real_method`(obj, name)

  Like getattr, but with a few extra sanity checks:

  - If obj is a class, ignore its methods
  - Check if obj is a proxy that claims to have all attributes
  - Catch attribute access failing with any exception
  - Check that the attribute is a callable object

  Returns the method or None.
