What is usage of the last comma in this code?

Question

for x in range(1, 11):
     print repr(x).rjust(2), repr(x*x).rjust(3),
     # Note trailing comma on previous line
     print repr(x*x*x).rjust(4)

Answer 1

It stops print from printing a newline at the end of the text.

As Dave pointed out, the documentation in python 2.x says: …. "A '\n' character is written at the end, unless the print statement ends with a comma."

UPDATE:

The documentation of python 3.x states that print() is a function that accepts the keyword argument end which defaults to a newline, \n.
