如何为pygame.draw.lines中的每一行使用不同的颜色

import pygame

# 初始化pygame
pygame.init()

# 设置窗口尺寸
width, height = 800, 600
screen = pygame.display.set_mode((width, height))

# 定义线段的起始点和终点坐标
points = [(100, 100), (200, 200), (300, 100), (400, 200)]

# 定义每条线段的颜色
colors = [(255, 0, 0), (0, 255, 0), (0, 0, 255), (255, 255, 0)]

# 绘制每条线段
for i in range(len(points) - 1):
    pygame.draw.line(screen, colors[i], points[i], points[i+1], 2)

# 刷新屏幕
pygame.display.flip()

# 游戏循环
running = True
while running:
    for event in pygame.event.get():
        if event.type == pygame.QUIT:
            running = False

# 退出pygame
pygame.quit()
