为什么向下的时候第一层循环时2，1，0，不是0，1，2？

你好，我这个为什么安装不了pynput呢

from pynput.keyboard import Key, Listener, KeyCode import random volume = 100 # 初始血量 print(f'初始血量是：{volume}') def on_press(key): global volume #血量为全局变量 if key == KeyCode.from_char('+'): # 按键 ‘+’ 处理部分 ran_valume = random.randint(1, 100) # 随机数 volume = volume + ran_valume # 加血 if volume > 100 : # 大于100，按100处理 volume = 100 print(f'血量为：{ volume} ') elif key == KeyCode.from_char('-'): # 按键 ‘-’ 处理部分 ran_valume = random.randint(1, 100) # 随机数 volume = volume - ran_valume # 减血 if volume < 0 : # 小于0，按0处理 volume = 0 print(f'血量为：{ volume} ') if volume == 0 : # 小于等于 0 结束 print('游戏结束') exit(-1) # 退出程序 elif key == KeyCode.from_char('q'): # 按 q 键退出程序 exit(-1) with Listener(on_press=on_press) as listener: # 按键处理 listener.join()

from pynput.keyboard import Key, Listener, KeyCode import random import sys #sys为结束整个程序 number = 100 def on_press(key): #gobal用来申明number为全局变量，可在函数内对函数外对number进行操作 global number if key == KeyCode.from_char('+'): number = number + int(random.randint(1,100)) if number >= 100: number = 100 print(f"已达到最大血量{number}，游戏继续") else: print(f"血量增加，现在血量：{number}，游戏继续") if key == KeyCode.from_char('-'): number =number - int(random.randint(1,100)) if number <= 0 : number = 0 print("血量已耗尽，游戏结束！") sys.exit() #此时自动结束并退出游戏 else: print(f"血量减少，现在血量：{number}，游戏继续") print() with Listener(on_press = on_press) as listener: listener.join()

为什么向下第一层循环采用0，1，2的时候，当x的坐标为[0][1]的时候按下s向下直接x的坐标变成了[1][2]?

测试没问题 # pip3 install pynput from pynput.keyboard import Key, Listener, KeyCode from random import randint initial_value = 100 print(f"初始血量为 ",initial_value) def on_press(key): global initial_value if key == KeyCode.from_char('+') : initial_value += randint(1, 100) if initial_value > 100: initial_value = 100 print(f"血量为: ",initial_value) elif key == KeyCode.from_char('-') : initial_value -= randint(1, 100) print(f"血量为: ",initial_value) if initial_value < 0: print("game over") exit() # 按esc退出 elif key == Key.esc : exit() with Listener(on_press=on_press) as listener: listener.join()
