[英]TypeError: 'int' object does not support item assignment, In threads
I have the following 2 modules:我有以下两个模块:
First Keyboard.py :第一个Keyboard.py :
import USB,evdev,threading,sys
global codigo
codigo = [1]
class Teclado:
def __init__(self,port):
self.puerto = USB.usb(port)
def iniciar_teclado(self):
p = threading.Thread(target=self.puerto.obtener_evento,args=(codigo))
p.start()
while 1:
if codigo[0] == evdev.ecodes.KEY_A:
print('A')
elif codigo[0] == evdev.ecodes.KEY_B:
print('B')
and USB.py :和USB.py :
import evdev,os,signal,sys
class usb:
def __init__(self,dev):
self.device = evdev.InputDevice(dev)
print(self.device)
def obtener_evento(self,c):
for event in self.device.read_loop():
if event.type == evdev.ecodes.EV_KEY and event.value == 1:
c[0] = event.code
So to pass by reference a variable in a thread, i use a list of a single element.因此,要在线程中通过引用传递变量,我使用了单个元素的列表。 As help, the following code has been taken as reference:作为帮助,以下代码已作为参考:
>>> c = [1]
>>> def f(list):
>>> list[0] = 'a'
>>> f(c)
>>> c[0]
'a'
but in my code, in the line但在我的代码中
c[0] = event.code
python tell me蟒蛇告诉我
TypeError: 'int' object does not support item assignment类型错误:“int”对象不支持项目分配
试试
p = threading.Thread(target=self.puerto.obtener_evento,args=(codigo,))
