Why is Python popular, while Lisp and Scheme aren't?

One reason is that Python has a lower threshold for learning. 
We can get a non-programmer productive in Python in 8-16 hours 
of training, but it takes 24-40 hours of training for Lisp.

My personal view: Lisp is more powerful, Python is more fun.
