迭代字典中的整数键时出错“int object is not subscriptable”Python 3

Question

我有字典数据 = {21: False, 22: False, 23: False, 31: False}

如果我检查这种类型，它会以 的形式出现，

我正在尝试迭代它并将值分配给 protobuff 变量，下面是我的示例代码

 def get_encoded_payload(self, payload):
        self.logger.debug("started")
        
         // my payload data looks like this 
        // payload= {21: False, 22: False, 23: False, 31: False}


        #set proto attributes of device status using json data
        device_status = DeviceStatusMsg()
        device = Device()

        #loop over current device status and set the each device state inot device proto
        for each_device in payload:

            device.type = each_device["device_type"] // Getting error here [ 'int' object is not subscriptable ]
            device.state = each_device["device_status"]

我正在尝试将 key, value 分配给 device.type and device.state

def get_encoded_payload(payload):

    for key,value in payload.items(): 
    # dictonery cannot be iterated the way you are iterating hence you are getting 
    # Getting error here [ 'int' object is not subscriptable ]
        b = key
        a = value
        print("a",a)
        print("b",b)
payload= {21: False, 22: False, 23: False, 31:False}

print(type(payload))
get_encoded_payload(payload)

您以错误的方式增加了 python 字典。我建议你阅读https://realpython.com/iterate-through-dictionary-python/。请查看上面的代码片段以供您参考。
