Why on earth would you recommend this outdated hack, when there's a true 
conditional operator?

     j = 3 if j >= 10 else j+1

Of course, many people feel like the conditional operator isn't worth 
the squished-up unreadability, but if someone asks for a conditional 
operator, at least show them one!
