Filename vs module in logging module

Assuming that a python file is named with a .py extension, would there ever be a reason that the module listed in the output of the logging module is not the filename itself (minus the extension)? For example:

Module (module)             == run
Filename (filename)         == run.py

Would be a variation of what I would get when using:

%(module)s , %(filename)s

Would there ever be a use-case where the above does not hold?

For the logging module, the module string is directly derived from the filename string:

try:
    self.filename = os.path.basename(pathname)
    self.module = os.path.splitext(self.filename)[0]
except (TypeError, ValueError, AttributeError):
    self.filename = pathname
    self.module = "Unknown module"

So, unless you are using custom logging code that alters these values on the log record after the fact, there is never a reason to see module as anything other than the base name of the file, without the extension.
