I wonder why there’s “None” after all those.

Don’t use print function, only use function sing_song(). Function print is in sing_song(), so you don’t need call it again.
I think function print in You’r example, is try to find argument’s or conditions for both sing_song(), and print can’t find it.

I’m only beginer, if i’m wrong, please correct me.
