Get signal names from numbers in Python

python signals

With the addition of the signal.Signals enum in Python 3.5 this is now as easy as:

>>> import signal>>> signal.SIGINT.name'SIGINT'>>> signal.SIGINT.value2>>> signal.Signals(2).name'SIGINT'>>> signal.Signals['SIGINT'].value2

python signals

There is none, but if you don't mind a little hack, you can generate it like this:

import signaldict((k, v) for v, k in reversed(sorted(signal.__dict__.items()))     if v.startswith('SIG') and not v.startswith('SIG_'))

python signals

The Python Standard Library By Example shows this function in the chapter on signals:

SIGNALS_TO_NAMES_DICT = dict((getattr(signal, n), n) \    for n in dir(signal) if n.startswith('SIG') and '_' not in n )

You can then use it like this:

print "Terminated by signal %s" % SIGNALS_TO_NAMES_DICT[signal_number]
