Running the command above prints out
ONE
TWO

but running

for i in range(10):
     print "ONE",
     time.sleep(0.2)

prints out
ONE ONE ONE ONE ONE ONE ONE ONE ONE ONE

like Hendrik mentioned adding comma to the end prints out on one line. 
But my problem problem wasn't printing on one line it was mathematical 
each time I printed on one line it was appending the print before. Which 
is all the above command does anyway. I had to apply some maths to solve 
the issue I was having which was printing out a progress bar. I Got it 
working though.
