How to pass parameter to a module?

[M-a-S]

I thought about the third module. It doesn't sound good.
I hoped there're some tricks with __dict__, frames and
other __...__ objects.

For now, this is what does the task:

# sub_2.py
''' The documentation will look like this:
     To set the size of dictionary and search depth,
     do before including (default values are shown):
        import string
        string.sub_2_dictionary_size = 10 # in megabytes
        string.sub_2_search_depth = 1000 # in nodes
        string.sub_2_max_responce_time = 100 # seconds
'''
import string # it's used in sub_2 anyway
# parameters
try: _DICT_SZ = string.sub_2_dictionary_size
except: _DICT_SZ = 10
try: _DEPTH = string.sub_2_search_depth
except: _DEPTH = 1000
try: _RTIME = string.sub_2_max_responce_time
except: _RTIME = 100
# now the stuff
def do_the_job():
   return "Processing with dict=%d depth=%d rtime=%d" % (_DICT_SZ,_DEPTH,_RTIME)
# EOF

# sub_1.py
import string # actually, some module, which is used in sub_2
string.sub_2_dictionary_size = 20 # megabytes
string.sub_2_search_depth = 5000 # nodes
# let's leave sub_2_max_responce_time default
import sub_2
print sub_2.do_the_job()
# EOF
