Why am I getting this TypeError?

[pitosalas]

Maybe it's early morning brain...The line called out is:

self.new_queue = Queue("New", sim)

and the error says:

Error:
TypeError: Queue.__init__() takes from 1 to 2 positional arguments but 3 were given

and the declaration says:

class Queue:
    def __init__(self, name: str, sim):

Can’t find how to do it. Tried but doesn’t seem to do the trick…

This example runs with no error.

class Queue:
    def __init__(self, name: str, sim):
        pass

new_queue = Queue("New", True)

The error message says that Queue is defined like this:

class Queue:
    def __init__(self, name=""):

I think Queue is not what you think it us. Is Queue a class you wrote, or is it imported?

[DeaD_EyE]

If you imported Queue from module queue, then you can use only one argument, which is the maxsize of the queue. The modules asyncio and multiprocessing modules have also a Queue implementation, which takes also maxsize.

If Queue is your implementation in a different module, then pay attention if you overload with an import your class.

from utils import Queue
from queue import Queue

# Queue is now form queue

# different order
from queue import Queue
from utils import Queue

# Queue is now form utils

Another possible error:

class Queue:
    def __init__(self, name, simu): ...

# later in code
class Queue:
    def __init__(self, name): ...

# calling now Queue, calls the latest definition of Queue,
# which takes only one argument. (the self is given implicit and is the instance of the class)
