for i in range(10):
    print i+'\n'


that does the same thing as
a = [0,1,2,3,4,5,6,7,8,9]
for i in a:
    print i+'\n'

or
a = range(10)
for i in a:
    print i+'\n'

Python's 'for' loop is not really meant as an iterator over a list of 
numbers
so this feature isn't built into the loop itself, you have to use the 
range function,
which just generates a list of numbers to iterate over.


Perhaps you should read an introductory Python tutorial.
Any one of them should cover the types of questions that people from 
other languages have about Python.
It sounds like you know how to program already, so the 'python for 
non-programmers' type of tutorial
may not be best-suited to you, but just look around.
If you have any more questions I'd be happy to answer them,
as would the rest of the list, I'm sure.
