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.

Answer 2

You can try this one as well;

tup = (1,2,3)
print("this is a tuple {something}".format(something=tup))

You can't use %something with (tup) just because of packing and unpacking concept with tuple.

Answer 3

Note that the % syntax is obsolete. Use str.format, which is simpler and more readable:

t = 1,2,3
print 'This is a tuple {0}'.format(t)

Answer 4

For python 3

tup = (1,2,3)
print("this is a tuple %s" % str(tup))

Answer 5

Talk is cheap, show you the code:

>>> tup = (10, 20, 30)
>>> i = 50
>>> print '%d      %s'%(i,tup)
50  (10, 20, 30)
>>> print '%s'%(tup,)
(10, 20, 30)
>>> 

Answer 6

t = (1, 2, 3)

# the comma (,) concatenates the strings and adds a space
print "this is a tuple", (t)

# format is the most flexible way to do string formatting
print "this is a tuple {0}".format(t)

# classic string formatting
# I use it only when working with older Python versions
print "this is a tuple %s" % repr(t)
print "this is a tuple %s" % str(t)
