TypeError: object() takes no parameters while importing a class file

i am trying to import a python class in another python file but i keep getting the error "TypeError: object() takes no parameters" but when written within the same file it works

i have tried the following

api.py

 from flask import Flask
 from flask_restful import Resource, Api
 from flask_restful import reqparse
 from flask import Flask, jsonify, request

 app = Flask(__name__)
 api = Api(app)

 class CreateUser(Resource):
     def post(self):
         try:
             parser = reqparse.RequestParser()
             parser.add_argument('email', type=str, help='Email address to create user')
             parser.add_argument('password', type=str, help='Password to create user')
             args = parser.parse_args()

             _userEmail = args['email']
             _userPassword = args['password']

             return {'Email': args['email'], 'Password': args['password']}

         except Exception as e:
             return {'error': str(e)}

main.py

from flask import Flask
import api as apii
from flask_restful import Resource, Api

CreateUser = apii.CreateUser(Resource)

app = apii.app
api = apii.api

api.add_resource(CreateUser, '/CreateUser')

if __name__ == '__main__':
    app.run(debug=True)

this is the error i get 

Traceback (most recent call last):
 File "main.py", line 5, in <module>
CreateUser = apii.CreateUser(Resource)
 TypeError: object() takes no parameters

Your class, CreateUser takes no parameters. You only need to put its parents in parenthesis when you first create the class. When you want to create an instance of the class, you simply call the class, and in this case it takes no parameters. The following should work for you.

CreateUser = apii.CreateUser()

if the CreateUser class had contained a def __init__(self, name) (for e.g.) method containing an initialisation parameter name- Then this would be reflected on instantiation of the class and would look something akin to the following:

x = CreateUser("JohnDoe")
