class Task:
image_window_list = []
def setId(self,Id):
      self.Id = Id

def setNoDownlink(self,NoDownlink):
      self.setNoDownlink = NoDownlink

def setTaskRequest(self,task_request):
      self.setTaskRequest = task_request

def setTaskProperty(self,task_property):
      self.setTaskProperty = task_property

def setTarget(self,task_target):
      self.setTarget = task_target

def getImageWindowList(self,window):
      self.getImageWindowList = Task.image_window_list.append(window)

a = Task()
window1 = 1
window2 = 2
print(type(window1))
print(type(window2))
a.getImageWindowList(window1)
a.getImageWindowList(window2)
print(a.image_window_list)

求问大佬，为啥a.getImageWindowList(window2)这一行会报TypeError: 'NoneType' object is not callable这个错误？

我改的那个代码你有运行了吗？那个就已经把 windows2 的值插进去了呀

没重新赋值吧？只是把元素插入一个列表而已

因为那个是我改了后的呀

你看看你没改之前的：

self.getImageWindowList = Task.image_window_list.append(window)
