Printing tuple with string formatting in Python

Question

So, i have this problem. I got tuple (1,2,3) which i should print with string formatting. eg.

tup = (1,2,3)
print \"this is a tuple %something\" % (tup)
         


        

Answer 1

>>> tup = (1, 2, 3)
>>> print "Here it is: %s" % (tup,)
Here it is: (1, 2, 3)
>>>

Note that (tup,) is a tuple containing a tuple. The outer tuple is the argument to the % operator. The inner tuple is its content, which is actually printed.

(tup) is an expression in brackets, which when evaluated results in tup.

(tup,) with the trailing comma is a tuple, which contains tup as is only member.
