   Jul 28, 2014 · The python 3 text "During handling" showing between every two exceptions in the chain of exception captures is quite exacerbating on this tangent. The extended syntax from the other answer side-steps this dubious message, while still making you emit a stacktrace hierarchy of exceptions even if you are fine with only the final one that you choose to raise.

   I stumbled upon a great way to rethrow exception with a little more info (python of course): try: do_something_dangerous() except Exception, e: e.args = "Some smart and helpful message. The original message:\n%s" % e.args raise It adds some info without changing the traceback, so it's both a bit more helpful and it doesn't change the location from which it was thrown to the except location.

   How do you handle exceptions in Python?

   • Python provides a powerful mechanism for handling exceptions, and one interesting technique is rethrowing exceptions with a different type using the raise statement. This allows developers to catch an exception, perform specific actions, and then propagate it up the call stack with a new exception type, if necessary.

   What is an exception in Python?

   • In Python, an exception is an event that occurs during the execution of a program and disrupts the normal flow of the program. It represents an error or an exception condition that the program encounters and cannot handle by itself. When an exception occurs, it is "raised" or "thrown" by the Python interpreter.

   Why is exception handling so important in Python?

   • This is even more important in Python than in many other languages, because Python uses exceptions so promiscuously—every for loop, every hasattr call, etc. is raising and handling an exception, and you don't want to see them.

   Apr 30, 2014 · In some languages and runtimes exception objects carry their own stack trace information, but in python the interpreter is responsible for capturing the state of the call stack when an exception occurs. To access this information a program can call the sys.exc_info() method, which returns a tuple with the last traceback in item 3.
