How to import instances of a Class in Python?-CodePudding

class Tweeter:

    def __init__(self, api_key, api_secret_key, bearer_token, access_token, access_token_secret ):
        self.api_key = api_key
        self.api_secret_key = api_secret_key
        self.bearer_token = bearer_token
        self.access_token = access_token
        self.access_token_secret = access_token_secret

        auth = tweepy.OAuthHandler(self.api_key, self.api_secret_key)
        auth.set_access_token(self.access_token, self.access_token_secret)

        self.api = tweepy.API(auth)

How can I import an instance of a class from the file in which the instance was created to another .py file.

For example: instance1 = Tweeter(xargument,yargument, zargument)

How do import and/or call the instance that I created in another file without having to import the detail that clutter up the code.

CodePudding user response：

Ideally, you'd use parameters to pass around your API client instance, rather than global application imports

You shouldn't need multiple (numbered) instances of it, either.

from classes import Tweeter  # for example

if __name__ == "__main__":
  t = Tweeter(...)
  some_function(t, some, other, args)

CodePudding user response：

from name_of_your_file_that_Tweeter_is_in import Tweeter

from file_x import Tweeter
instance1 = Tweeter(xargument,yargument, zargument)

CodePudding user response：

As long as you initialize your class instance of Tweeter outside of a function or method, then you should be able to import that instance. Keep in mind that all the code that is not within a function or class is ran whenever you import from that file. For example:

# tweeter.py
Class Tweeter:
    ...


# This code is ran whenever this file is imported from another file
tweeter = Tweeter(<arguments to pass to the __init__ function>)



# my_file.py


from .tweeter import tweeter # Assuming both files are in the same directory

# now you have the same class instance from the tweeter.py file
print(tweeter)
