Re: [Tutor] Getting started with PyGTK [Receiving Error]

[Russell Smith]

Make sure you installed the theme engine 'pixmap' or whichever gtk package
that has the theme engine you are missing. Google search for the gtk
packages. Look here
http://askubuntu.com/questions/66356/gdk-gtk-warnings-and-errors-from-the-command-lineand
you will see a very similar problem with a solution which I bet will
help you.

Cheers

Re: [Tutor] Pygame installation problems

[Russell Smith]

I would google 'pygame download' and look at the first hit. You are right
to add the import but you need to download the files still.

[Tutor] Help - server health check reporter

[Russell Smith]

Hey guys,



I’m trying to put together a script using urllib2, smtplib and
stripogram/html2text which will use a healthcheck url, read the response
after loading it and then email me the results without any unwanted html
tags. I was able to do that but, when I get a timeout on one of the servers
the script breaks with an error response. I’m very new to python and I don’t
know how to take that error and have it sent as well, instead of breaking
the script. Any advice or links I can check out that might be helpful? I
appreciate it.


I can include the python code if needed though at this point I'm sure it is
not very "pythonic". {smile}


Regards,

-russ
