Python 3.x 使用evdev InputDevice退出python程序会导致错误
我正在尝试使用evdev将控制器作为输入设备。当我退出程序时,会收到一条错误消息,指出delete方法(super)至少需要一个参数。我已经看过了,但我们无法找到一个解决方案来妥善处理这个问题 该方案:Python 3.x 使用evdev InputDevice退出python程序会导致错误,python-3.x,controller,evdev,Python 3.x,Controller,Evdev,我正在尝试使用evdev将控制器作为输入设备。当我退出程序时,会收到一条错误消息,指出delete方法(super)至少需要一个参数。我已经看过了,但我们无法找到一个解决方案来妥善处理这个问题 该方案: # import evdev from evdev import InputDevice, categorize, ecodes # creates object 'gamepad' to store the data # you can call it whatever you like g

print(gamepad)
# evdev takes care of polling the controller in a loop

# filters by event type
if event.type == ecodes.EV_KEY and event.code == 308:
break
if event.type == ecodes.EV_ABS and event.code == 1:
print(event.code, event.value)

print(event.code, event.value)
# print(categorize(event))
if event.type == ecodes.EV_KEY:
print(event.code, event.value)
当我使用特定的键时,我会中断循环,导致以下错误消息:
Exception TypeError: TypeError('super() takes at least 1 argument (0 given)',) in <bound method InputDevice.__del__ of InputDevice('/dev/input/event5')> ignored
异常TypeError:忽略中的TypeError('super()至少接受1个参数(给定0)')
使用^C
退出时也会发生同样的情况。
您知道如何正确处理退出吗?简单地说,evdev正在等待事件发生,而您突然中断了循环 要正确退出执行,请删除break语句,关闭设备并结束脚本
[...]
for event in gamepad.read_loop():
if event.type == ecodes.EV_KEY and event.code == 308:
gamepad.close() #method of ..yourpythonlib/evdev/device.py
quit()
[...]
要使用^C
快速退出而不出现错误,您仍然需要使用“try-except块”关闭evdev输入设备
for event in gamepad.read_loop():
try:
[...] if event [...]
except KeyboardInterrupt:
gamepad.close()
raise
