How to test python function, that has two or more input()'s inside?

I need to test some python 3 code, and I got stuck testing function with few input()'s.

Example:

def two_answers():
    if input("Input 'go' to proceed") != "go":
        return two_answers()
    else:
        while input("Input 'bananas' to proceed") != "bananas":
            print("What?!")
    print("You've just gone bananas!")

For functions with one input i use:

def test_some_function(self):
    codefile.input = lambda x: 'u'
    codefile.some_function() . . . .

And then:

def teardown_method(self, method):
    codefile.input = input

To revert inputs back.

But here it won't work. Help!
