Get signal names from numbers in Python

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

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

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