Why one of these examples work but not the other?

Question

I am a begginer in Python. I am writting this exercise to practice and found one way to do it, when I thought about doing it another way, it didn't work. It's probably a organization error, but I can't see it. Please take it easy to explain.

shuffle(list)
print('The new order is {}'.format(list))

That works.

print('The new order is{}'.format(shuffle(lista)))

That doesn't. I know it's simple but I have no one here to help me solve that doubt. Thanks.

You need to supply your error traceback, variable values and `shuffle` realization code. — vishes_shell, Jun 14 '18 at 17:36

I expect that shuffle shuffles the list in place, but returns None as its value. Your second syntax requires a new version of the list to be returned.

Also, note that list is a built-in type. Don't use pre-defined identifiers as your personal variables.
