Kevin Bacon game with breath-first search

There are a couple ways to correct this. The first way is calling the cvor's attribute that stores the name (ime, I believe):

for movie in graf:
    print(movie.ime)

To simplify that, you could create a function that does the same thing and use map():

def return_movie_name(movie):
    return movie.ime

print(map(return_movie_name, graf))

Or, you can add __str__() and __repr__() methods to cvor to return the movie name when the object is printed:

class cvor:
    __slots__ = ('ime','susjed')

    def __str__(self):
        return self.ime

    def __repr__(self):
        return self.__str__()

print(graf)
