Question

I have a tuple m = ('ring', 5) and I want to print it out as ring 5 .

I have tried print %s %f, %m and I get an error. What am I doing wrong?

Answer 1

>>> m = ('ring', 5)

what you were trying to do

>>> print "%s %f" % m
ring 5.000000

Except %f means float and you want %d for int :

>>> print "%s %d" % m
ring 5

Answer 2

Use format it is more elegant

print '{0} {1}'.format(*m)

Answer 3

m = ('ring', 5)
print m[0], m[1]

prints

ring 5

Answer 4

>>> m = ('ring', 5)
>>> for element in m:
        print element,
ring 5

This might work.
