你的代码有几个错误，我来帮你修改一下：

import pygame
pygame.init()
screen = pygame.display.set_mode([800, 600])
pygame.display.set_caption("画图5h(1.0)")
radius = 15
mousedown = False
UnFinished = True

white = 255, 255, 255
red = 255, 0, 0
yellow = 255, 255, 0
blue = 0, 0, 225
black = 0, 0, 0
green = 0, 128, 0

screen.fill(blue)
pygame.draw.rect(screen, white, (0, 0, 50, 50), 0)
pygame.draw.rect(screen, red, (50, 0, 50, 50), 0)
pygame.draw.rect(screen, yellow, (150, 0, 50, 50), 0)
pygame.draw.rect(screen, blue, (200, 0, 50, 50), 0)
pygame.draw.rect(screen, black, (350, 0, 50, 50), 0)
pygame.draw.rect(screen, green, (100, 0, 50, 50), 0)

UnFinished = False
color = white
while UnFinished:
    for event in pygame.event.get():
        if event.type == pygame.QUIT:
            UnFinished = False
        elif event.type == pygame.MOUSEBUTTONDOWN:
            mousedown = True
        elif event.type == pygame.MOUSEBUTTONUP:
            mousedown = False
        if mousedown:
            spot = pygame.mouse.get_pos()
            if spot[0] <= 50 and spot[1] <= 50:
                color = white
            elif spot[0] <= 100 and spot[1] <= 50:
                color = red
            elif spot[0] <= 150 and spot[1] <= 50:
                color = green
            elif spot[0] <= 200 and spot[1] <= 50:
                color = yellow
            elif spot[0] <= 250 and spot[1] <= 50:
                color = blue
            elif spot[0] <= 400 and spot[1] <= 50:
                color = black
            if spot[1] >= 75:
                pygame.draw.circle(screen, color, spot, radius)
    pygame.display.update()

pygame.quit()

这个代码使用 Pygame 创建了一个简单的画图程序，你可以使用鼠标点击不同的颜色方块，然后在屏幕上绘制出对应颜色的圆形。按下鼠标并拖动可以连续绘制圆形，松开鼠标则停止绘制。按下窗口的关闭按钮可以退出程序。希望对你有帮助！如果还有其他问题，请随时提问。
