类里面的函数调用问题
class Task:def __init__(self):
self.image_window_list = []
def setImageWindowList(a,b):
if (a > b):
print(1)
def getImageWindowList(c,d):
return Task.setImageWindowList(c,d)
e = Task()
print(e.getImageWindowList(2,1))
求助大佬，为啥会报TypeError: getImageWindowList() takes 2 positional arguments but 3 were given这个错误？怎样改正可以使得e.getImageWindowList(2,1)的输出结果为1呢？ 因为实例调用实例方法会将实例本身传递进去，所以得加个 self 形参来接收实例本身
class Task:
def __init__(self):
self.image_window_list = []
def setImageWindowList(self, a,b):
if a > b:
return1
def getImageWindowList(self, c,d):
return self.setImageWindowList(c,d)
e = Task()
print(e.getImageWindowList(2,1))
