If the file system location you are looking for is near code you are using or can import, python's "inspect" may be your friend. >>> import inspect So, if your object is, for example, a view method and you need the directory where another method is defined for your view, you can >>> sourcefilepath = inspect.getsourcefile(self.otherMethod) Here's another example for clarification. It works, but is not particularly useful: Let's say we want to know the file system location where Decimal.normalize is defined. >>> from inspect import getsourcefile >>> from decimal import Decimal We can get the location directly: >>> getsourcefile(Decimal.normalize) '/usr/lib64/python2.5/decimal.py' Or, if we just want the location of the class: >>> getsourcefile(Decimal) '/usr/lib64/python2.5/decimal.py' or, we can get the location from an instance: >>> d = Decimal('0.12') >>> getsourcefile(d.normalize) '/usr/lib64/python2.5/decimal.py' >From there, standard os.path functions can get you locations relative to the location given.
