Key Press Not Working

[brandon wallace]

 
I am trying to catch a key press but it is not working. How can I fix this 
code? There is no error message so there is no error message to do a search on.
I am using Python3.5 64-bit inside the terminal.

while True:
key = input("Enter a letter: ")
if key == ord('q'):
 break
 
 The loop keeps running even though I have pressed the letter 'q'.

Try: Except: evaluates to True every time

[brandon wallace]

I have this code that tests a server to see if it is listening on port 123 runs 
and evaluates to True every time. Even if the server does not exist but it is 
not supposed to do that. I am getting no error message at all. What is going on 
with this code?
 
 

#!/usr/bin/env python

import socket

hostname = ["192.168.1.22", "192.168.1.23", "200.168.1.24", "19.0.0.0"]
port = 123

def check_udp(hosts, port_num):
    '''Test the UDP port on a remove server.'''
    s = socket.socket(socket.AF_INET, socket.SOCK_DGRAM)
    for host in hosts:
    try:
    s.connect((host, port_num))
    return "Port 53 is reachable on: %s" % host
    except socket.error as e:
    return "Error on connect: %s" % e

check_udp(hostname, port)

Try Except Specific Error Messages

[brandon wallace]

Hi,
 
I am try to get more specific error messages using try/except.
I ran this code with the cable unplugged to see the error message. I got 

#!/usr/bin/env python3

import urllib.request

webpage = urllib.request.urlopen("http://fakewebsite.com/";)
text = webpage.read().decode("utf8")


I got two errors. This:
[]
socket.gaierror: [Errno -2] Name or service not known

and this:
[]
urllib.error.URLError: 

I tried this but got more error messages.
try:
webpage = urllib.request.urlopen("http://fakewebsite.com/";)
text = webpage.read().decode("utf8")
except URLError as err:
print("URLError: " + str(err))

How do I wrap urllib.request with try/except?
