我只是清理了lambda和comma函数，它对我来说就像预期的那样工作。因为您似乎不熟悉maya ui/class，所以我用一些以DW开头的行注释清理了整个脚本：因此，您可以找到如何更轻松地管理maya ui！你知道吗
不要犹豫，看看部分，我有很多贴士，希望对你有所帮助：
import maya.cmds as cmds
import maya.OpenMaya as om
import maya.mel as mel
import sys
import math
from functools import partial


def create(rigType, sideColor, isStretch, *args):

    # DW : refreshed every time by property that is executing before being passed
    if rigType == 0:
        print('IK/FK mode')
    elif rigType == 1:
        print('IK mode')
    elif rigType == 2:
        print('FK mode')

    # DW : in this state of the script, it will return always 7 because there is no refresh query
    #      so you can see to pass outside your class some arguments
    #      below an example for an alternative of property
    print('color picked is {}'.format(sideColor))

    # DW : in this example the function for getting the status is passed
    #      it is different from property because we still use to execute the command
    if isStretch():
        print('rig is stretchy')
    else:
        print('no stretch')

    # Dw : note that if you create an instance of your window inside a variable :
    # ui = rigCreator()
    # ui.ikfkPick is something you can print at any moment to debug
    # any variable with 'self' would be replaced by 'ui' in this case 


class rigCreator:

    # DW : default colour, self don't need to be specify but it is like so
    #      personally I put the important parameters or parameters that set default values on top
    #      it is easier when parsing the code few month later
    sideColor = 7  #: DW : don't hesitate to do inline comment to say this is RED color (im followng google doctstring https://sphinxcontrib-napoleon.readthedocs.io/en/latest/example_google.html)
    isStretch = 0
    ikfkPick = 0  #: pick IK/FK option,  1 for IK, 2 for FK

    def __init__(self, *args):

       #self.startFunction()
        self.window = "uiWindow"
        self.title = "Rigging Tool Bipeds"
        self.winSize = (150, 200)
        self.createUI()

    def createUI(self):

            cmds.deleteUI(self.window, wnd=True)
