Hello,
with a Class you can do it also.
import os
class Module:
def __init__(self, module):
self._name = module.__name__
print('Got module', self._name)
self._file = module.__file__ if hasattr(module, '__file__') else
'(built-in)'
self._module = module
def __repr__(self):
return "<module '{}' from '{}'>".format(self._name, self._file)
def __getattr__(self, key):
ret = getattr(self._module, key)
if isinstance(ret, types.ModuleType):
print('Attribute {} is in the module {}'.format(key,
self._name))
return Module(ret)
else:
print('Attribute {} is not a module. It\'s a {}'.format(key,
type(ret)))
return ret
def __getitem__(self, key):
return self.__getattr__(key)
os_wrapped = Module(os)
sub1 = 'path'
sub2 = 'sys'
sub3 = 'version'
value = os_wrapped[sub1][sub2][sub3]
print(value)
Maybe this code breaks other stuff. Also error handling is not present.
