  I cannot personlly help but a google search
  using the following phrase seems promising

URLError:

2022-02-12 Thread Shaozhong SHI
The following is used in a loop to get response code for each url.

print (urllib.request.urlopen(url).getcode())

However, error message says: URLError: 

Python 3.6.5 is being used to test whether url is live or not.

Can anyone shed light on this?

Regards,

David

So apparently that ability was added in Excel 97.

Yes, these days you would use Office 365 for that kind of functionality,
but that didn't exist at that time (neither did cloud storage systems).

Network file systems like NFS or SMB did exist, though, and people
wanted (or at least MS thought they wanted) to collaborate on Excel
files. So Excel provided a way to do that.

That was sort of the point: That Excel was not *always* single-user.
There have been ways that multiple users could simultaneously edit the
same file for 25 years.

I'm pretty sure that that worked entirely through the file system. So
the only thing stopping you from implementing it in a different program
was the lack of documentation (as was typical for MS in the 1990's).

But again, this wasn't my point. My point was that Excel files are
designed to be used only by a single process isn't true.

getaddrinfo is the function that resolves a domain name into an IP
address. If that fails, either the domain name doesn't exist or you have
a problem with your DNS setup.

Things to test:

* Can you resolve the domain name to an address (try «nslookup» or
  «host» or «dig» depending on your OS)?
* Can you access the whole URL with a different tool like «wget» or
  «curl»?

What that's saying is that it couldn't look up the domain name to get
the corresponding address. Most likely, that means you either don't
have DNS available, or the DNS server said that it couldn't find that
server. (Whether that's true or not. It's always possible for the DNS
server to be wrong.) So, if you can fairly safely assume that you have
a fully-functioning internet connection (for instance, if other URLs
can be fetched successfully), the most reasonable interpretation of
this is that the URL is, in some way, broken.

I suspect that errno 11001 is a Winsock error, in which case it would
mean "Host not found". On my Linux system, I get a chained exception
that says "Name or service not found". Most likely, you can find this
information further up in the traceback.

However, error message says: URLError: 

11001 == WSAHOST_NOT_FOUND.

Look in any 'winsock.h' header:
  #define WSAHOST_NOT_FOUND (WSABASEERR+1001)
