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.
