In Python 2.x, exception objects do not have any reference to their
traceback; this is one of the reasons Twisted has the Failure class, which
encapsulates both. (In Python 3 exceptions do have their tracebacks
attached.) Thus, if you want the traceback logged, you should do something
like:
from twisted.python import log
try:
1/0
except Exception as e:
# Log the last exception that occurred, including its traceback:
log.err(None, "An error occurred.")
Or:
from twisted.python import log, failure
try:
1/0
except Exception as e:
f = failure.Failure()
log.err(f, "An error occurred.")
