How to make a fully transparent window with pygame

This window will cover the full screen of the pc completely transparent. To make you see that is there, I showed some text onto it. It has no frame, so it is completely invisible. Press Esc to close it.

import pygame
import win32api
import win32con
import win32gui

pygame.init()
info = pygame.display.Info()
w = info.current_w
h = info.current_h
screen = pygame.display.set_mode((w, h), pygame.NOFRAME) # For borderless, use pygame.NOFRAME
done = False
fuchsia = (255, 0, 128)  # Transparency color
dark_red = (255, 100, 0)

# Create layered window
hwnd = pygame.display.get_wm_info()["window"]
win32gui.SetWindowLong(hwnd, win32con.GWL_EXSTYLE,
                       win32gui.GetWindowLong(hwnd, win32con.GWL_EXSTYLE) | win32con.WS_EX_LAYERED)
# Set window transparency color
win32gui.SetLayeredWindowAttributes(hwnd, win32api.RGB(*fuchsia), 0, win32con.LWA_COLORKEY)
font = pygame.font.SysFont("Arial", 72)
text = []
text.append((font.render("Invisible background", 0, dark_red), (0, 10)))
text.append((font.render("Press Esc to close the window", 0, dark_red), (0, 100)))
def show_text():
    for t in text:
        screen.blit(t[0], t[1])

while not done:
    for event in pygame.event.get():
        if event.type == pygame.QUIT:
            done = True
        if event.type == pygame.KEYDOWN:
            if event.key == pygame.K_ESCAPE:
                done = True

    screen.fill(fuchsia)  # Transparent background
    show_text()
    # pygame.draw.rect(screen, dark_red, pygame.Rect(30, 30, 60, 60))
    pygame.display.update()

pygame.quit()

You can see the text on top of the invisible window

Make the window opaque
