Python 3.9 type hints

[El-Naizin]

Hello, I came across this repository, which was very useful to me, so thank you for the code 😄

• I noticed there were no python 3.9 type hints, which help me code, especially for the unreal types. (vscode does not understand the comment style type hints).

• I removed the inheritance from (object) in classes, which were used in python 2 but are not needed in python 3.

• I applied the black formatter, but I can remove that if you prefer to only have the type hints and nothing else.

Other considerations that could be useful, but would need a bit of code change so I didn't include it yet (I can if you want it):

• For enumerations in python, you can Inherit from the Enum class

from enum import Enum

class RenderStatus(Enum):
    """
    Enum class to represent render job status
    """

    UNASSIGNED = "un-assigned"
    READY_TO_START= "ready to start"
    IN_PROGRESS= "in progress"
    FINISHED = "finished"
    ERRORED = "errored"
    CANCELLED = "cancelled"
    PAUSED = "paused"

• For the RenderRequest class, you could use a dataclass

from dataclasses import dataclass
class RenderRequest(dataclass):
    """
    An object representing request for an Unreal render job sent from a
    machine to the request manager (renderManager.py)
    """
    uid: str
    """unique identifier, server as primary key for database"""
    name: str
    """job name"""
    owner: str
    """the name of the submitter"""
    worker: str
    """the name of the worker to render the job"""
etc...
