Print always adds a newline unless you put a comma at the end.
Unfortunately that results in a character being lost too so I
recommend using a tab at the front like this:
for n in range(20):
print "\tAt line: %5s" % n
Also be aware that on sime systems \r is the newline character
in which case the method I use is to backspace the number of
characters occupied by my data (5 in the case above) using
\010.
Something like this slightly flawed example:
>>> def f():
... print "Label: ",
... for n in range(5):
... print "%s%3s" % ('\010' * 3, n),
...
I'll leave debugging it as an excercise for the reader! :-)
