我正面临一个问题,我不知道这是从哪里来的。 由于我的代码太长,我将只共享产生此错误的函数和使用它的行(当然,如果需要,我当然可以共享其他部分)
class Label(object):
#constructor
def __init__(self, data, id, filefullpath, AGE, counter):
self.counter = counter
self.filefullpath = filefullpath
self.data = data
self.object_id = id
self.data_length = len(data)
self.AGE = AGE
# GUI
self.root = Tk()
self.root.title("CHOOSE A LABEL")
#Create a listbox with a scrollbar
self.listbox = Listbox(self.root)
type = ['Indifined','a','b','c']
for ind, val in enumerate(type):
self.listbox.insert(ind, val)
self.listbox.bind('<<ListboxSelect>>', self.save)
self.listbox.pack()
Button(self.root, text = "OK" , command = self.root.destroy).pack(side = 'left')
self.root.mainloop()
def get_selected_label(self):
""" get the label entered by the user """
return(self.listbox.get(self.listbox.curselection()))
def save(self):
"""
Save the label entered by the user
"""
# get the label
label = self.get_selected_label()
if len(label) > 0:
for k in range(self.AGE +2): # plus 2 to include age=-1 and age = 0
Informations = Get_Informations(self.data, self.filefullpath, self.counter - k)
Id = Informations.Id()
age = Informations.age()
for ind, val in enumerate(Id):
if self.object_id == val:
age = age[ind]
if age <= self.AGE:
self.data[self.counter - k]["super_clusters"][ind]["label"] = label
else:
break
else:
pass
for k in range(self.counter +1 , len(self.data)):
Informations = Get_Informations(self.data, self.filefullpath, k)
Id = Informations.Id()
age = Informations.age()
if self.object_id in Id :
for ind, val in enumerate(Id):
if self.object_id == val :
age = age[ind]
if age != -1:
self.data[self.counter + k]["super_clusters"][ind]["label"] = label
else:
break
else:
pass
else:
# the track disappeared
break
这是Python返回的错误:由于在调用它时我没有传递任何要保存的参数,我真的不明白该消息。
Exception in Tkinter callback
Traceback (most recent call last):
File "C:\ProgramData\Anaconda3\lib\tkinter\__init__.py", line 1702, in __call__
return self.func(*args)
TypeError: save() takes 1 positional argument but 2 were given
我先谢谢你。
答案 0 :(得分:2)
来自effbot(重点是我):
Tkinter提供了一种强大的机制,可让您自己处理事件。对于每个小部件,您都可以将Python函数和方法绑定到事件。
widget.bind(event, handler)
如果与事件描述匹配的事件发生在窗口小部件中,则给定的处理程序称为,带有描述事件的对象。
因此,您在bind
中定义的 handler 函数将与事件对象一起调用。该对象包含诸如生成事件的窗口小部件,事件类型等内容。在effbot链接中的事件对象下查找完整列表。
您当然可以决定对此对象不做任何事情,但是您的函数具有可以接受它,例如:
def save(self, event):
