zope.dottedname 3.4.0

Resolver for Python dotted names.

The zope.dottedname.resolve module provides a function for resolving dotted names. Dotted names are resolved by importing modules and by getting attributes from imported modules. Names with leading dots are relative.

To illustrate, we’ll use the dotted name resolver to access objects in the os module:

>>> from zope.dottedname.resolve import resolve
>>> resolve('os.path.split').__name__
'split'

Here, we used an absolute name. We can also using a relative name:

>>> resolve('.split').__name__
Traceback (most recent call last):
...
ValueError: relative name without base module

But we need to provide the module the name is relative to:

>>> resolve('.split', 'os.path').__name__
'split'

>>> resolve('..system', 'os.path').__name__
'system'

>>> resolve('...datetime', 'os.path').__name__
'datetime'
