My code:
try:
subprocess.check_call(['ping', '-w1', ip])
except CalledProcessError:
print 'System', ip, 'is not responding. Exiting....'
sys.exit(4)
else: return None
The result:
Traceback (most recent call last):
File "./testing.py", line 222, in <module>
main()
File "./testing.py", line 170, in main
ip, port, endTime = parse_command_line(args)
File "./testing.py", line 111, in parse_command_line
ip = do_ip(args)
File "./testing.py", line 85, in do_ip
ping_ip(ip)
File "./testing.py", line 44, in ping_ip
except CalledProcessError:
NameError: global name 'CalledProcessError' is not defined
I didn't think Python return errors needed to be defined. I'll work
around it with call_output, but what the heck is going on here? What do
I not understand?
