> both using os module where should I put the "import os"? In both files?
You don't really have a choice, you have to import os in both files. Python will only load the os module into memory once, but the import statements are needed to add the os module to the c and m module namespaces. The code in c.py cannot 'see' the code in m.py, even if it was imported by m.py. The import command is not like #include in C, it is not a code dump. -m -- http://mail.python.org/mailman/listinfo/python-list
