I am sure this is old news, the syntax of python is crazy to me.
There I said it, I'm sure I'll get over it or around it.
I was trying to make a whois script work and was unable.
May be someone with lint-like eyes can tell what's wrong.
Using xemacs I had hoped that python mode would do more
for syntax problems, maybe I'm just not using python mode
correctly in xemacs??
