一些使用示例

In [1]: from dotted_name_resolver import DottedNameResolver

In [2]: r = DottedNameResolver()

In [3]: r.resolve('os.path')
Out[3]: <module 'posixpath' from
'/Users/marca/python/virtualenvs/dotted_name_resolver/lib/python2.7/posixpath.pyc'>

In [4]: r.resolve('os.path.exists')
Out[4]: <function genericpath.exists>

In [5]: r.resolve('dotted_name_resolver.DottedNameResolver.maybe_resolve')
Out[5]: <unbound method DottedNameResolver.maybe_resolve>

In [6]: import os.path

In [7]: r.resolve(os.path.exists)
