Dude ... I just finished this, found the same solution ... EXCEPT, I included a "if not isdigit()" check into the return statement, because my dumb-ass though that the "moOse" example in the description had a zero instead of a capital 'o'... so I thought that we had to make sure that if a number is included, function returns False. Once I finished and saw your solution, I was looking at it for like solid 3 minutes, asking myself why is this here if it obviously doesn't fufill one of the requirements, before finally realizing that I confuzed 0 and O .... **** me.

Oh yea, sorry. Since I got to this page right after finishing, I just assumed that you have to finish to get here. Thanks for info though.
