extract_stack

traceback

function (source)

extract_stack(f=None, limit=None)

Extract the raw traceback from the current stack frame.

The return value has the same format as for extract_tb().  The
optional 'f' and 'limit' arguments have the same meaning as for
print_stack().  Each item in the list is a FrameSummary object,
and the entries are in order from oldest to newest stack frame.
