[Tutor] Exception Handling

[Alan Gauld]

socket.gaierror: [Errno 11004] getaddrinfo failed

...

ResolveHostname = socket.gethostbyname(name)
print(ResolveHostname)
newFile.write(ResolveHostname + "\n")
print(ResolveHostname)
newFile.write("No resolution available for %s" % (name) + "\n")

You are catching herror but your code is resulting in gaierror.

Add socket.gaierror to your except line.

except (socket.herror, socket.gaierror):
newFile.write("No resolution available for %s" % (name) + "\n")

see if that works

Just a followon remark: always try to print the exception when you're not
certain of what it will be or what to do with it. So I'd augument Alan's code
like this:

except (socket.herror, socket.gaierror) as e:
newFile.write("No resolution available for %s: %s" % (name, e) + "\n")
