Question

Is there opportunity to join my types using:

str.join()

I have my class:

class Slice(object):
    def __init__(self, start, end):
        self.__start = start
        self.__end = end

    def __str__(self):
        return '{0}:{1}'.format(self.__start, self.__end)

    def __repr__(self):
        return "'{}'".format(str(self))

What should i override to perform this kind of code:

','.join(Slice(1, 2), Slice(3, 4))

And get a result like this:

'1:2,3:4'

Answer 1

Nothing.

','.join(str(x) for x in (Slice(1, 2), Slice(3, 4)))
