My ultimate goal is a function I'd put in my main library which other functions could leverage, something like: function_in_another_file(arg): logger.info(my_main_module.render_calling_info(inspect.stack(), inspect.currentframe()) # Now do the work -- https://mail.python.org/mailman/listinfo/python-list

My question is: let's say I wanted to add a type hint for my_frame. my_frame: some_class_name = inspect.currentframe() What would I put for some_class_name? "frame" (without quotations) is not recognized, Nor is inspect.frame. We know Python code is executed in an execution frame. (https://docs.python.org/3/reference/executionmodel.html?highlight=frame) We are told "Frame objects Frame objects represent execution frames." (https://docs.python.org/3/reference/datamodel.html?highlight=frame). The word "represent" conflicts with the idea of "are". 'Under the hood' inspect calls sys._current_frames() (https://docs.python.org/3/library/sys.html?highlight=frame). That code is: def _getframe(*args, **kwargs): # real signature unknown """ Return a frame object from the call stack. If optional integer depth is given, return the frame object that many calls below the top of the stack. If that is deeper than the call stack, ValueError is raised. The default for depth is zero, returning the frame at the top of the call stack. This function should be used for internal and specialized purposes only. """ pass Which rather suggests that if the sys library doesn't know the signature, then neither typing nor we mere-mortals are going to do so, either. Theory: the concept of a frame does not really exist at the Python-level (remember "represents"). Frames (must) exist at the C-level (https://docs.python.org/3/c-api/frame.html?highlight=frame#c.PyFrameObject) of the virtual-machine - where typing is not a 'thing'. It's an interesting question.
