In order to protect our wikis against excessive spam, we are using textchas (short questions and answers) which users have to answer before they can commit their changes or sign up to the sites. I found that short Python snippet work well, since they require domain knowledge that you cannot simply look up in Wikipedia, e.g. "l = [1,2,3]; del l[1]; l[0] ==". Would be great if you could send me some more ideas for such textchas (please don't post the answers to this list; just posting the questions is fine). PS: Please make sure that the questions work in both Python 2 and 3 and produce the same or at least similar answers.
