我有这段代码 从集合中导入namedtuple
Device = namedtuple('Device', ['Name', 'Timestamp'])
#add samples
deviceList = [Device(Name = "alo", Timestamp="00000"), Device(Name = "lilo", Timestamp="1111"), Device(Name = "piko", Timestamp="2222")]
def findDeviceByName(listOfDevices, DeviceName):
print(listOfDevices)
for x in listOfDevices:
if (DeviceName == x.Name):
return True
else:
return False
print(findDeviceByName(deviceList, "lilo")) #returnes False even if lilo is in deviceList
print(len(deviceList)) #prints 3
出于某种原因,此foreach循环在列表的第一个元素处停止,但是您可以清楚地看到列表中有3个元素,即使len()如此表示
不确定为什么会这样,如果有人有任何想法,请告诉我 感谢您的问候和问候!
