You can suppress the newline by ending the print statement with a comma, but you will still get the 

print 1,
print 2,
print 3

will print
1 2 3

You can get full control of the output by using sys.stdout.write() instead of print. Note the 
arguments to write() must be strings:

import sys

Or you can accumulate the values into a list and print the list as Lutz has suggested:

l = []
print ''.join(map(str, l))

where map(str, l) generates a list of strings by applying str() to each element of l:
  >>> map(str, l)
['1', '2', '3']

and ''.join() takes the resulting list and concatenates it into a single string with individual 
elements separated by the empty string ''.
