Python API design for existing Java API

I am new to python and I have to design a Python API(version - 2.7) similar to an existing Java API

Python version - 2.7

The Java API is as follows

public interface Process<T> {

  Future<T> create(Client<T> client)

  //Other methods
}

public interface Client<T> extends Serializable {

  T execute(ClientContext c)

  //Other methods
}

public interface ClientContext {

  File createFile(String path)

  //Other methods
}

The equivalent Python API design that I have come up with is

Approach1

class Process:
  __metaclass__ = ABCMeta

@abstractmethod
def create(self, client):
    pass

class Client:
  __metaclass__ = ABCMeta

@abstractmethod
def execute(self, context):
    pass

class ClientContext:
  __metaclass__ = ABCMeta

@abstractmethod
def createFile(self, path):
    pass

Approach2

Can I use closures to directly pass the context to the create function of Process class so that I can eliminate the Client class

Note The create method of Process class will process async tasks which can be done using concurrent.futures package from python.

I want to know which of the 2 approaches is good

Also open to better approaches as well
