Works fine for me...

For a quickie test, I copy/pasted this code into Idle, and it works.

I suspect you are trying to run this as a script -- but remember, when running interactively 
(directly in Python or in Idle) the return values are displayed automatically.  This is NOT true 
when running as a program, you have to specifically print the return values (or save them in a 
variable to access them later).  Change your calling line to:

print(front_x(['bbb', 'ccc', 'axx', 'xzz', 'xaa']))
