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.
__name__
always contains the full name of the module. (Other than __main__
on main, of course.)
Try using the __name__
attribute of the module.
A simple way of retrieving the full module name within its package:
print(__file__)
the other answers don't account for __name__
becoming __main__
for the program entry point or don't handle it properly.
this works for me:
def python_module() -> str:
stack = inspect.stack()
module = inspect.getmodule(stack[1][0])
if module is None:
raise ValueError("module not found")
res = module.__name__
if res != "__main__":
return res
package = module.__package__
if package is None:
package = ""
mfname = module.__file__
if mfname is None:
return package
fname = os.path.basename(mfname)
ext = ".py"
if fname.endswith(ext):
fname = fname[:-len(ext)]
if fname == "__init__":
return package
return f"{package}.{fname}"
