Huh?
 >>> x = ['h', 'i', '!']
 >>> print ''.join(x)
hi!

I don't see any problem there. In the most cases you could also build up 
a string accumulatedly.

I'd guess they think about print "",;print "moo" (print a blank string, 
do not skip line, print another one) to preserve the "softspace". As far 
as I get your problem, you don't really have to think about it.
