Python 3.8+signalfunction

signal.strsignal()

enums and information

Returns the OS description of a signal: 'Interrupt' for SIGINT, 'Killed' for SIGKILL. Useful for readable messages.

Syntax

signal.strsignal(signalnum)

The text comes from libc and depends on the system: Linux and macOS phrase it differently, and on Windows many signals return None — so compare numbers or .name in code and keep strsignal for messages. A negative subprocess return code (-9) means death by signal: strsignal(-returncode) explains it to a human. A number out of range raises ValueError.

Examples

import signal
print(signal.strsignal(signal.SIGINT))  # → Interrupt
print(signal.strsignal(9))  # → ? Killed на Linux
try:
    signal.strsignal(1000)
except ValueError as e:
    print(e)  # → signal number out of range
