Below is the provided pygame zero code:
If possible please share the screenshot of the Mu editor
page.
Please do the code in Mu editor and set mode to pygame zero
because i cannot understand if done in other.
Thank you the provided code is below and we need to modify
it:

cell = Actor('gridbox.png', anchor=('left', 'top'))
cell.x = 0 * BLOCK_SIZE
cell.y = 0 * BLOCK_SIZE
spaceship = Actor("player1", anchor=('left', 'top'))
spaceship.x = 4.5*BLOCK_SIZE
spaceship.y = 9*BLOCK_SIZE

alien2.x = 3*BLOCK_SIZE
alien2.y = 2*BLOCK_SIZE
# You need to declare the necessary variables/properties.

Assignment 3 - Space Invaders Part 2 1. The first thing we need to do is to make the aliens move automatically. Let the aliens move from left to right. Once they reach the right border of the screen, they should re-enter the screen from the left border. Each alien should have a speed property, and the value of the speed is 1. (Hint: Refer to Assignment 1.) 2. We need to make the spaceship move when the user presses on the keyboard buttons. Modify the code so that the spaceship Actor moves 2 pixels to the right every time any key is pressed and held. (Oh yeah! Our spaceship is faster than the aliens'.) The movement should be continuous. The movement should stop the moment the player releases the key. To do that, you need to define the on_key_down(key), on_key_up(key), and update() functions. You also need to add a new property (variable) to the spaceship called dx. (Hint: Refer to Lab 2.) 3. If the spaceship moves out of the right border of the screen, we also want the spaceship to re- enter the screen from the left border. 4. We want to load the current highest score from a local disk file. The filename is "highScore.txt". This file is provided. You may modify the number in the file to any integer, and your program should still work. After you decompress (i.e., extract) the ZIP folder, you should be able to see this:
After you decompress (i.e., extract) the ZIP folder, you should be able to see this: M х highScore - Notepad File Edit Format View Help 123000 images highScore invaders2.py Important issue: In Python 3 mode, the data file should always be placed in the same directory as the Python program (the PY file). However, in Pygame Zero mode, the situation is different. A. If the version of Mu is 1.1.0, the data file should be placed in the same directory as the Python program. B. If the version of Mu is 1.0.2 or 1.0.3, the data file should be placed in the system directory of Mu. There is an easier way to figure out where you should place the data file. Launch Mu, and load "invaders2.py". Then click on the menu button "Images". A file explorer (finder for Mac OS) will pop up. It will show you a directory named "images". This directory may be the directory of the images of Space Invaders (Situation-A), or it may be the system directory of the default images of Mu (Situation-B). In either case, you should place "highScore.txt" in the parent directory of the images directory that you see.

Write code after the declarations of the spaceship and alien variables to read the number from the "highScore.txt" file. You need to declare the necessary variables for file operations. The highest score should be an integer. (Hint: Refer to the lecture of I/O.) 6. We want to display the highest score on top of the screen when the game is being played. Write code in the draw() function so that the screen looks like the image below. Part of the code is provided.
