How to check if a remote url is reachable using Python?

Question

Python

I would like to know how to use Python(3.3) to determine if a certain url address is available to me?
When calling a command urllib.request.urlopen('адрес')with a non-existent address, an error is generated. How to modify this code, or how it is possible to replace this call so that the program does not stop its work.

Answer 1

try:
    urllib.request.urlopen('адрес')
except URLError:
    print 'Адреса не существует'

Answer 2

Get to know the exceptions mentioned above, a powerful thing to know

Answer 3

Thanks for the help
, only in my example it turns out that you need to do the following:

try:
        urllib.request.urlopen('адрес')
except:
        print("Oops!  That was no valid adress.  Try again...")

when adding a condition to except, the error text is still displayed
