How to use errno?

This betrays a sign of dogmatism, of my way or the highway kind of attitude.

I disagree. It shows that the python community is different from the perl community. In perl, any particular thing you want to do, can be done in dozens of different ways. If you ask 10 perl programmers how to do something, you'll get 15 different ways to do it.

The Python community is built more around having a small number of obvious solutions, instead of many wacky ways to do something.

All that said, it looks like the original question was answered. If it hasn't, please explain what problem you're trying to solve, what you've tried, and what errors you're getting. Otherwise, it looks like this thread is devolving into troll territory, and it'll be locked if we continue in that direction.
