Using tuples with .format in python

Question

while using the .format() with text filling, I encounter this error.

what I have:

tuple = ('a', 'b', 'c')
text = "Hi {} hello {} ola {}"
#command I tried to run
text.format(tuple)

The output I am aiming for:

 Hi a hello b ola c

the error I get:

IndexError: tuple index out of range

not sure how to fix this!

Answer 1

You want to use an iterable unpacking:

>>> t = (1, 2, 3)
>>> "{}, {}, {}".format(*t)
'1, 2, 3'

Side note: Do not use tuple as a variable name, as that is a reserved Python built-in function (i.e. tuple([1, 2, 3])).

Answer 2

@FelipeFaria's answer is the correct solution, the explanation is that in text.format(tuple) you are essentially adding the entire tuple to the first place holder

print(text.format(tuple))

if worked, will print something like

Hi (a, b, c) hello { } ola { }

format is expecting 3 values, since it found only one it raise tuple index out of range exception.
