Why is svn:ignore ignored?

I just ran

svn add myfolder/*

To add all the files in there to my repo. It added the .pyc files too. I'm looking at my svn:ignore now and it says:

*.pyc
*~

Should that not have prevented those file开发者_运维知识库s from being checked in?

No, it should not. svn:ignore prevents files from being shown in the svn status. But if you're adding the files explicitly - then svn will add them, of course.
