For homework let's practice subclasses. In your repository make two files. One named baserobot.py. That file describes a class BaseRobot that needs to have the following properties and methods.

The BaseRobot class should have the following properties:

• self.x: The x position of the robot
• self.y: The y position of the robot

And the following methods:

• __init__: The constructor should take in two numbers and set them to be the x position of the robot (self.x) and the y position of the robot (self.y).
• move: Move takes in two numbers in increases that x and y positions of the robot by those numbers
• beep: Beep prints the word beep to the console.
• __str__: returns a string that says the position of the robot.

The code for the __str__ method should look like this:

def __str__(self):
    return f"Robot is at position ({self.x}, {self.y})"

Then have another file, armbot.py, that describes a subclass of BaseRobot called ArmBot. An ArmBot can do all the things that BaseRobot can do, but with these differences:

The ArmBot class should have properties it inherits from the BaseRobot and the following properties:

• self.arm_position: The position of the arm of the robot
• self.claw_open: A boolean value indicating if the claw is open or closed

The Armbot should have the following methods:

• __init__: In the init method it should call the init of the BaseRobot class using super, but also set a value for its arm position, self.arm_position to be zero. Also, it sets a value for the claw indicating that the claw is closed. Do this by setting self.claw_open to False.
• move_arm: This method takes in a number and increases the arm_position by that amount.
• grab_claw: This method sets the value of self.claw_open to be False.
• release_claw: This method sets the value of self.claw_open to be True.
• __str__: Reports the position of the robot and status of the arm and the claw.

The code for the __str__ method should look like this:

def __str__(self):
    return super().__str__()+" with arm at position {self.arm_position} and claw {'open' if self.claw_open else 'closed'}"
