找不到的修复：只接受1个参数（给定2个）

Question

我最近接触了python，已经遇到了“只接受1个参数（给定2个）”的问题。在

我到处都在找它，而且大部分时间都在读《失踪》来增加自我部分。在

尽管我补充说我不能解决它，我是不是错过了女人的重点？在

import maya.cmds as cmds

class ButtonPress:

    def __init__(self):
        self.value = 0

    def buildUI(self):
        window = cmds.window(title = 'Press Button', w = 100, h = 50)
        columnL = cmds.columnLayout(w = 100, h = 50)
        cmds.button(parent = columnL, label = 'Press me', w = 100, h = 50, command = self.__increaseAndPrint)
        cmds.showWindow(window)

    def __increaseAndPrint(self):
        self.value += 1
        print self.value

谢谢你的帮助。在

编辑： 我将maya脚本编辑器中的类用于：

ButtonPress（）.buildUI（）

我得到： 错误：\uUu increaseAndPrint（）只接受1个参数（给定2个） 当按下UI按钮时。在

对不起。在

import maya.cmds as cmds

class ButtonPress:

    def __init__(self):
        self.value = 0

    def buildUI(self):
        window = cmds.window(title = 'Press Button', w = 100, h = 50)
        columnL = cmds.columnLayout(w = 100, h = 50)
        cmds.button(parent = columnL, label = 'Press me', w = 100, h = 50, command = self.__increaseAndPrint)
        cmds.showWindow(window)

    def __increaseAndPrint(self, *args):
        # maya throwing through ui a default bool argument as last.
        # you need *args to catch and dismissed it
        self.value += 1
        print self.value
