dynamically adding some of one module's functions to another

[Gabriel Rossetti]

Hello everyone,

I'm trying to import some modules into another's namespace (network_utils)

network_utils.py:

import utils
import constants as main_const
from services import constants as srv_const
from plugins import constants as plg_const

#
# Import all the message creation functions
#
f = dict([ (f, eval("utils." + f)) for f in dir(utils) if
f.startswith("create") ])
__builtins__.update(f)
del utils

#
# Create a virgin namespace
#
class constants:
"""
An aggragation of L{constants},
L{services.constants}, &
L{plugins.constants}
"""
pass

#
# Import all the constants into the new namespace
#
f = dict([ (f, eval("main_const." + f)) for f in dir(main_const) if
f.isupper() ])
constants.__dict__.update(f)
del main_const
f = dict([ (f, eval("srv_const." + f)) for f in dir(srv_const) if
f.isupper() ])
constants.__dict__.update(f)
del srv_const
f = dict([ (f, eval("plg_const." + f)) for f in dir(plg_const) if
f.isupper() ])
constants.__dict__.update(f)
del plg_const
now, if I import network_utils somewhere, and try to call
network_utils.myFunction() I get :

>>import network_utils
network_utils.myFunction

Traceback (most recent call last):
File "<console>", line 1, in <module>
AttributeError: 'module' object has no attribute 'myFunction'

but if I try to access the constants class:

>>from network_utils import constants
constants.NO_DATA_TYPE

'none'

it works, how come?

Thank you,
Gabriel
