Yeah thanks! It's working but I have actually one more question.
When I am running your program when should I press the buttons because on the terminal it appears the image below dev-to-uploads.s3.amazonaws.com/i/...

It looks like it may be crashing. It prints "Clear..." when it's clearing the buffer. At that point the screen should start flashing. Do you have an ide you can run it where you might see more information? I think I used a Thonny.

Did the screen flash?

yes, according to
epd.init() # initialize the display
print("Clear...") # print message to console
epd.Clear(0xFF)

So the eink display flashes? After it clears the display it should put a message to the console. That message comes from the drivers. If that's not happening, check the waveshare repo to see if they have a new version.
