Actually, I disagree with David's solution somewhat --- I think that
the pythonic way to do this is as follows:

Firstly, you can use a list comprehension to convert each integer into
a separate string.  If you don't know about list comprehensions, you
can read about them in any python tutorial.

 x = [1, 2, 3, 4, 5]
 y = [str(i) for i in x]
 y
['1', '2', '3', '4', '5']

Then you can use the .join() method of strings to join them into a
single line.  In this case, the separator is a space, ' ':

 z = ' '.join(y)
 z
'1 2 3 4 5'

If you want to put one number on each row, you can use the newline
character '\n' as a separator instead:

 '\n'.join(y)
'1\n2\n3\n4\n5'
 print '\n'.join(y)
1
2
3
4
5

HTH!
