Are you using 'print' to get the output? Please see the following code
and note what the 'print' lines which have a comma at the end produce.
The 'print' statement is not always suitable for producing closely
controlled output. Consider constructing the exact string you want and
using a 'write' method.
$ cat ./jjj.py
#!/usr/bin/python
s = 'now'
print s
print s,
print s
x = s.replace('now', '')
print '%s' % x,
print 'then'

$ ./jjj.py
now
now now
then
