Question

I am using libcurl to DL a webpage, then i am scanning it for data and doing something with one of the links. However, once in a while the page is different then i except thus i extract bad data and pycurl throws an exception. I tried finding the exception name for pycurl but had no luck.

Is there a way i can get the traceback to execute a function so i can dump the file so i can look at the file input and see were my code went wrong?

sys.excepthook may help you here, where you can set a global exception handler. I am not sure how pycurl exceptions are handled, it being a binding library, but it will probably work to reassign it to a generic function. Something like:

>>> import sys >>>  >>> def my_global_exception_handler(type, value, traceback): ...     print traceback ...     sys.exit() ...  >>> sys.excepthook = my_global_exception_handler >>> raise <traceback object at 0xb7cfcaa4> 

This exception hook function could easily be an instance method that has access to the file that needs dumping.
