In python:
IDLE 1.1.3
>>> number = 3
>>> furryanimal = 'rat'
>>> print 'There are', number, 'of ways to skin a', furryanimal
There are 3 of ways to skin a rat

You have to remember that spaces are added automatically.
Printing a comma list is quite common in informal and preliminary work
and sometimes in finished work when its output is good enough.

This gives more control over exact format of output.
Some people may also prefer having variables grouped together at end,
especially if they 'grew up' on C (for instance) rather than Basic.
