如何在Pygame中画出1/4的圆？

import pygame

pygame.init()

screen = pygame.display.set_mode((width, height))

pygame.draw.arc(screen, color, rect, start_angle, stop_angle, thickness)

pygame.draw.arc(screen, color, rect, 0, 90, thickness)

pygame.display.flip()

import pygame

# 初始化Pygame
pygame.init()

# 创建屏幕
width = 800
height = 600
screen = pygame.display.set_mode((width, height))

# 绘制1/4的圆
color = (255, 0, 0)  # 红色
rect = pygame.Rect(100, 100, 200, 200)  # 外接矩形
start_angle = 0  # 起始角度
stop_angle = 90  # 结束角度
thickness = 2  # 线条粗细
pygame.draw.arc(screen, color, rect, start_angle, stop_angle, thickness)

# 刷新屏幕
pygame.display.flip()

# 保持窗口打开
running = True
while running:
    for event in pygame.event.get():
        if event.type == pygame.QUIT:
            running = False

# 退出Pygame
pygame.quit()
