MicroPython中保存高分出现TypeError: unsupported types for __ge__: 'int', 'list'的原因

我在Raspberry Pi Pico上开发俄罗斯方块游戏时，尝试实现高分保存功能，但持续报错，无法定位代码问题，查阅相关方案也未解决。

报错代码片段 #

def game_over_screen():
    pgb.fill_rect(240-240,240-240,240,240,PicoGameBoy.color(0,0,0))
    pgb.fill_rect((GRID_OFFSET+GRID_COLS+1)*BLOCK_SIZE+1,16*BLOCK_SIZE,
                  BLOCK_SIZE*7,BLOCK_SIZE*2,
                  TEXT_BACKGROUND_COLOR)
    pgb.text("LINES",(GRID_OFFSET+GRID_COLS+2)*BLOCK_SIZE+1,16*BLOCK_SIZE+1,TEXT_COLOR)
    pgb.text("%8s" % lines,(GRID_OFFSET+GRID_COLS+2)*BLOCK_SIZE+1,17*BLOCK_SIZE+1,TEXT_COLOR)
    if score >= highscore:
        highscore.pop(0)
        highscore.append(score)
    pgb.fill_rect((GRID_OFFSET+GRID_COLS+1)*BLOCK_SIZE+1,16*BLOCK_SIZE,
                  BLOCK_SIZE*7,BLOCK_SIZE*2,

    pgb.text("%8s" % highscore,(GRID_OFFSET+GRID_COLS+2)*BLOCK_SIZE+1,17*BLOCK_SIZE+1,TEXT_COLOR)

    #pgb.fill_rect(60,90,120,240,BLACK)
    pgb.center_text("GAME OVER",WHITE)
    pgb.show()
    while True:
        time.sleep(0.500)

错误输出信息 #

Traceback (most recent call last):
  File "<stdin>", line 608, in <module>
  File "<stdin>", line 409, in game_over_screen
TypeError: unsupported types for __ge__: 'int', 'list'

问题原因与修复方案 #

• 错误根源：代码中if score >= highscore:这一行，score是整数类型，而highscore是列表类型，Python不允许直接用>=运算符比较整数和列表，因此触发类型错误。
• 修复步骤：
  1. 修正比较逻辑：如果highscore是存储高分的列表（比如按从低到高排序），需要和列表中的具体分数比较，比如和列表里的最低分（第一个元素）对比，将代码改为：

     if score >= highscore[0]:
         highscore.pop(0)
         highscore.append(score)
         # 可选：对列表重新排序，保持从低到高顺序
         highscore.sort()
     

  2. 修正高分显示：当前代码pgb.text("%8s" % highscore,...)会把整个列表打印出来，不符合显示需求，应该显示列表中的最高分，改为：

     pgb.text("%8s" % max(highscore),(GRID_OFFSET+GRID_COLS+2)*BLOCK_SIZE+1,17*BLOCK_SIZE+1,TEXT_COLOR)
     

     或者如果列表是按从低到高排序，也可以用highscore[-1]取最后一个元素（最高分）。
  3. 初始化检查：确保highscore初始化时是包含整数的列表，比如highscore = [0]或highscore = [1000, 800, 500]这样的初始高分值。
