Incorrect. Here's a copy-and-paste from an interactive session using that code: >>> import sys >>> from traceback import extract_stack >>> >>> varPassed="varName get" >>> >>> def MyFunc(varPassed): ... try: ... raise None ... except: ... frame = sys._getframe(1) ... print extract_stack(frame,2)[0][3] ... >>> MyFunc(varPassed) None >>> > the print statement returns the full function call including parameters > as they were written in the script (variable names and all) I'm afraid not. I don't know what testing you did, but it doesn't work as you think it works. Also, I notice that you've called the variable local to the function the same name as the variable in the outer scope. What happens when you do this? >>> x = "something else" >>> MyFunc(x) None > at first glance the solution i came up with seems to be in general the > same as the one presented there, are there any portability issues > you're aware of? Yes. sys._getframe is a PRIVATE function, which means it is subject to change without notice. You're using an internal function clearly marked as private. It is unlikely to even exist at all in other implementations of Python (e.g. Jython, IronPython, PyPy, CLPython, etc.), and it might not even exist in future versions of CPython. > also, when can one _not_ get the name? When the object doesn't have a name at all, or when it has multiple names. Which is "the" name? -- Steven -- http://mail.python.org/mailman/listinfo/python-list
