Function Details

[hide private]

get_traceback()

Return the traceback of the exception that is currently being handled by the system. First, we create an "in-memory" file object and assign the traceback string to it by calling the print_exc function. We then close the file and return the string. If no exception is currently being handled, None is returned.

Example usage:

>>> from enomalism2 import exceptions
>>> exceptions.get_traceback()

Returns: String/None

The current traceback string.

Raises:

None - No exceptions are raised by this function.
