traceback

Under what situations would I want to use one over the other? What is the difference between: >>> import inspect >>> print(inspect.getouterframes(inspect.currentframe())) [(<frame object at 0x8fc262c>, '<stdin>', 1, '<module>', None, None)] And: >>> import traceback >>> traceback.extract_stack() [('<stdin>', 1, '<module>', None)] Update: Another: >>> import sys >>> print(sys._getframe().f_trace,sys._getframe().f_code) (None, <code object <module> at 0x8682a88, file "<stdin>", line 1>) I do not understand the nuances here: Stack Frame Frame Object Stack Trace update 2, a bit of time since the

I've got a piece of code similar to this: import sys def func1(): func2() def func2(): raise Exception('test error') def main(): err = None try: func1() except: err = sys.exc_info()[1] pass # some extra processing, involving checking err details (if err is not None) # need to re-raise err so caller can do its own handling if err: raise err if __name__ == '__main__': main() When func2 raises an exception I receive the following traceback: Traceback (most recent call last): File "err_test.py", line 25, in <module> main() File "err_test.py", line 22, in main raise err Exception: test error From

I've set up the following for loop to accept 5 test scores. I want the loop to prompt the user to enter 5 different scores. Now I could do this by writing the input "Please enter your next test score", but I'd rather have each inputted score prompt for its associated number. So, for the first input, I'd like it to display "Please enter your score for test 1", and then for the second score, display "Please enter your score for test 2". When I try to run this loop, I get the following error: Traceback (most recent call last): File "C:/Python32/Assignment 7.2", line 35, in <module> main() File "C

In numpy we can do np.seterr(invalid='raise') to get a traceback for warnings raising an error instead (see this post ). Is there a general way for tracing warnings? Can I make python to give a traceback, when a warning is raised? mgab You can get what you want by assigning to warnings.showwarning . The warnings module documentation itself recommends that you do that, so it's not that you're being tempted by the dark side of the source . :) You may replace this function with an alternative implementation by assigning to warnings.showwarning . You can define a new function that does what

I am trying to get hold of a traceback object from a multiprocessing.Process. Unfortunately passing the exception info through a pipe does not work because traceback objects can not be pickled: def foo(pipe_to_parent): try: raise Exception('xxx') except: pipe_to_parent.send(sys.exc_info()) to_child, to_self = multiprocessing.Pipe() process = multiprocessing.Process(target = foo, args = (to_self,)) process.start() exc_info = to_child.recv() process.join() print traceback.format_exception(*exc_info) to_child.close() to_self.close() Traceback: Traceback (most recent call last): File "/usr/lib
