Python 3.2+inspectfunction

inspect.getattr_static()

static attribute lookup

Looks up an attribute without running code: properties, __getattr__ and __getattribute__ are not invoked. Meant for tools that only inspect an object.

Syntax

inspect.getattr_static(obj, attr[, default])

Plain getattr, and even hasattr, executes a property with all its side effects. getattr_static returns what sits in the dictionaries: the property object rather than its value, a function rather than a bound method, a staticmethod rather than a function. Attributes produced by __getattr__ are invisible to it: you get AttributeError or the default.

Examples

import inspect
class P:
    @property
    def val(self):
        print('property executed')
        return 42
    def __getattr__(self, name):
        return 'dyn:' + name
p = P()
print(getattr(p, 'val'))  # → property executed / 42
print(type(inspect.getattr_static(p, 'val')).__name__)  # → property
print(getattr(p, 'zzz'), inspect.getattr_static(p, 'zzz', 'нет'))  # → dyn:zzz нет

import inspect
class S:
    @staticmethod
    def sm(): pass
    def m(self): pass
print(type(inspect.getattr_static(S, 'sm')).__name__, type(S.sm).__name__)
# → staticmethod function
print(type(inspect.getattr_static(S(), 'm')).__name__, type(S().m).__name__)
# → function method
