Error while calling function in Python3.5

Question

I am trying to run the repository of IqoptionAppi

While I am trying to run the command: api.getcandles(1,60,25)
the following error occured:

api.getcandles(1,60,25)
Traceback (most recent call last):
  File "<stdin>", line 1, in <module>
TypeError: __call__() takes 3 positional arguments but 4 were given

I have seen the function and is something like this:

from iqoptionapi.ws.chanels.base import Base


class GetCandles(Base):
    """Class for IQ option candles websocket chanel."""
    # pylint: disable=too-few-public-methods

    name = "candles"

    def __call__(self, active_id, duration, amount):
        """Method to send message to candles websocket chanel.

        :param active_id: The active/asset identifier.
        :param duration: The candle duration (timeframe for the candles).
        :param amount: The number of candles you want to have
        """
        data = {"active_id": active_id,
                "duration": duration,
                "chunk_size": 25,
                "from": self.api.timesync.server_timestamp - (duration * amount),
                "till": self.api.timesync.server_timestamp}

        self.send_websocket_request(self.name, data)

The repository says it works in Python 2.7 but I tried installing it on Python 3.5, it still worked except the above issue. Guide me where exactly I missed.

I believe you are providing self as a first argument. When calling a class member method, python does it for you. — Sianur, Jun 26 '18 at 09:58
@Sianur But I am not using it while calling the function you can see it in my example. — Jaffer Wilson, Jun 26 '18 at 10:00
@miindlek ok see this: `api = IQOptionAPI("iqoption.com", "name@email.com", "Passwordhidden")`, This is the way I have create the object. — Jaffer Wilson, Jun 26 '18 at 10:10
well, i've installed it locally and there are only 2 parameters (except `self`): `active_id`, `duration` — Azat Ibrakov, Jun 26 '18 at 10:33
@AzatIbrakov I have share link on the repository in the question please check the first line of question. — Jaffer Wilson, Jun 26 '18 at 10:37
my local version is [0.5](https://github.com/n1nj4z33/iqoptionapi/blob/0.5/iqoptionapi/ws/chanels/candles.py) and it seems to be [the latest on PyPI](https://pypi.org/project/iqoptionapi/0.5/#history) — Azat Ibrakov, Jun 26 '18 at 10:40
@AzatIbrakov May be. I do not know the version let me check it out — Jaffer Wilson, Jun 26 '18 at 11:09
@AzatIbrakov exactly the same version. `Version: 0.5`. Please note I am using python 3.5 ok — Jaffer Wilson, Jun 26 '18 at 11:12

Problem here is that iqoptionapi/ws/chanels/candles.py module from latest PyPI version differs from Github's master branch version and there is no amount parameter (it seems to be equal to 2).

In master branch:

def __call__(self, active_id, duration, amount):
    ...
    "from": self.api.timesync.server_timestamp - (duration * amount),
    ...

In 0.5 version:

def __call__(self, active_id, duration):
    ...
    "from": self.api.timesync.server_timestamp - (duration * 2),
    ...

So we can ignore this parameter (do not pass it at all and use default value 2) or install master branch version using git like

> pip install --upgrade git+https://github.com/n1nj4z33/iqoptionapi.git@master

Here we are using --upgrade flag since version didn't change so we force to reinstall package.

Or another option: you can ask repo owner to release new version and publish it on PyPI.

Afer updating, I am getting the error: `TypeError: unsupported operand type(s) for /: 'NoneType' and 'int'` — Jaffer Wilson, Jun 26 '18 at 11:59
