如何从Maya（Python）的Arnold菜单运行功能？

Question

代码：

import maya.cmds as cmds
import maya.mel as mel
mainWindow = mel.eval('$temp=$gMainWindow')

mainWindowMenus = cmds.window(mainWindow, query = True, menuArray = True)

masterMenus = cmds.menu(mainWindowMenus[-2], query = True, itemArray = True)
masterMenusLabel = cmds.menu(mainWindowMenus[-2], query = True, label = True)

cmds.menuItem(masterMenus[-3], query = True, label = True)
cmds.menuItem(masterMenus[-3], query = True, command = True)

arnoldMenu = cmds.menu(masterMenus[-3], query = True, itemArray = True)
for x in arnoldMenu:
    print cmds.menuItem(x, query = True, label = True)
    print cmds.menuItem(x, query = True, command = True)

此查询Arnold主菜单的标签和命令（只要插件已加载且是右侧的第二个菜单）我的输出看起来像这样：

空行是分隔符类型的menuItem，因此没有命令。那么如何通过Python运行这些命令？当我单击menuItems来运行代码时，总是收到如下错误消息：

Windows找不到'htmlfile \ shell \ open \ command'。确保正确输入名称，然后重试。

Answer 1

类似这样的东西：

<function callback at 0x0000021B812B24A8>

是这样的函数对象：

def hello():
    print "Hello"

f = hello

现在f包含您好的函数对象：

<function hello at 0x0000019493BCE7B8> 

并且可以通过使用“（）”执行，因此请尝试：

f()

结果应为“ Hello”。
