Sort of....not really When a module is imported the following things happen
import ONE a module object (dict essentially) named ONE is created. This is the module ONE.py's namespace. The module object is added to sys.modules the code in the object is executed inside the ONE dict (namespace) now if ONE has at the top import os ONE is able to use the line os.path.join (mydir, "foo.txt") If however we do not have the line import os we will get an error as the namespace of one does not have a reference to the module object of os as an example import your one.py and run pprint.pprint(sys.modules['one'].__dict__) You will see what a virgin namesapce looks like - there is a lot in there but it boils down to __builtins__, __doc__, __file__, __name__ and whatever you define (_-dict__) care notes --------------- You can easily get into circular references with imports, simply because code at the module level (ie not in a function or class) will be executed at the first import - and if it calls code that is in the next module which waits on code in the first etc etc. So as you said, put everything into classes or functions or be very careful with your imports.
