python3 : how to use for loop and if statements over class attributes?

Question

我有以下类(class):

class equipment:
    def __init__(self, name, location, status):
        self.name = name
        self.location = location
        self.status=status 

class device(equipment):
    def __init__(self, name, location,status):
        super().__init__(name, location,status)


device1 = device("device1 ", (5, 2), 0)
device2 = device("device2", (10, 2), 0)
device3 = device("device3", (15, 3), 0)
device4 = device("device4", (5, 5), 0)

all_devices = ['device1', 'device2', 'device3', 'device4']

并基于另一个代码:我得到 status_devices=[1,0,1,1] 所以我想通过使用 for 循环和 if 语句来更新原始状态(仅打印 status=1 的设备)，

for n in range(0, 4):
    all_devices[n].status=status_devices[n]

这种方式给了我错误:str对象没有属性状态

谢谢

Answer 1

导致您提到的错误的问题是您有

all_devices = ['device1', 'device2', 'device3', 'device4']

而不是

all_devices = [device1, device2, device3, device4]

(也就是说，您创建了一个字符串列表，而不是一个设备对象列表。)
