TypeError: object takes no parameters

Question

I'm trying to create a code that utilizes the __iter__() method as a generator, but I am getting an error saying:

TypeError: object() takes no parameters.

Additionally, I am unsure whether my yield function should be called within try: or within the main() function

I am fairly new to Python and coding, so any suggestions and advice would be greatly appreciated so that I can learn. Thanks!

class Counter(object):

    def __init__(self, filename, characters):
        self._characters = characters
        self.index = -1

        self.list = []
        f = open(filename, 'r')
        for word in f.read().split():
            n = word.strip('!?.,;:()$%')
            n_r = n.rstrip()
            if len(n) == self._characters:
                self.list.append(n)

    def __iter(self):
        return self

    def next(self):
        try:
            self.index += 1
            yield self.list[self.index]

            except IndexError:
                raise StopIteration
            f.close()

if __name__ == "__main__":
    for word in Counter('agency.txt', 11):
        print "%s' " % word

...your `__init` etc. methods lack two underscores at the end. It's `__init__`. That might cause the error. — Roberto, Apr 25 '16 at 01:25
The indentation and forgotten __init__ underscored were the issue! Thank you all so much for helping me with my silly typos. — D. Lopez, Apr 25 '16 at 03:24

You mistyped the declaration of the __init__ method, you typed:

def __init

Instead of:

def __init__

Oh wow, I can't believe I missed that. Glad that that issue was just a dumb typo, however, now the error is telling me: TypeError: 'Counter' object is not iterable. Thoughts? – D. Lopez Apr 25 '16 at 02:26

@D.Lopez Same thing for `def __iter__` – Pierre Barre Apr 25 '16 at 02:27

Use yield for function __iter__:

class A(object):
    def __init__(self, count):
        self.count = count

    def __iter__(self):
        for i in range(self.count):
            yield i

for i in A(10):
    print i

In your case, __iter__ maybe looks something like this:

def __iter__(self):
    for i in self.list:
        yield i

TypeError: object takes no parameters
