Python - get full package module name

For verbose debug messages in my application I'm using a function that returns a helpful prefix. Consider the following example:

import inspect

def get_verbose_prefix():
"""Returns an informative prefix for verbose debug output messages"""
s = inspect.stack()
module_name = inspect.getmodulename(s[1][1])
func_name = s[1][3]

return '%s->%s' % (module_name, func_name)

def awesome_function_name():
print "%s: Doing some awesome stuff right here" % get_verbose_prefix()

if __name__ == '__main__':
awesome_function_name()


This outputs:

test->awesome_function_name: Doing some awesome stuff right here





My issue is: When I have a module in a package, for instance 'myproject.utilities.input', the module name returned from
get_verbose_prefix
is still just 'input', not 'myproject.utilities.input'. This drastically reduces the helpfulness of the prefix in large projects when there can be several 'input' modules in different submodules all working together.

So my question is: Is there a simple way of retrieving the full module name within it's package in Python? I'm planning on expanding the
get_verbose_prefix
function to check for '__init__.py' files in the parent directories of the module to extrapolate it's full name, but first I'd like to know if there's an easier way to do it.

Answer

__name__ always contains the full name of the module. (Other than __main__ on main, of course.)
