1. python的安装

在Eclipse中安装pydev环境，pydev更新地址为： http://pydev.org/updates

2. 配置python环境：

打开Eclipse菜单Window/Preferences，在PyDev中配置Python Interpreter的设置如下：

注意要添加devkit\other\pymel\extras\completion\py目录。这样才有提示。

添加python代码：

import sys
import maya.OpenMaya as OpenMaya
import maya.OpenMayaMPx as OpenMayaMPx

kPluginCmdName = "spHelloWorld"

#command
class scriptedCommand(OpenMayaMPx.MPxCommand):
    def __init__(self):
        OpenMayaMPx.MPxCommand.__init__(self)
        
    #invoked when the command is run.
    def doIt(self, argList):
        print "hello World!"
        
#creator
def cmdCreator():
    return OpenMayaMPx.asMPxPtr(scriptedCommand())

#initialize the script plug-in
def initializePlugin(mobject):
    mplugin = OpenMayaMPx.MFnPlugin(mobject)
    try:
        mplugin.registerCommand(kPluginCmdName, cmdCreator)
    except:
        sys.stderr.write("Failed to register command: %s\n" % kPluginCmdName)
        raise
    
#uninitialize the script plug-in
def uninitializePlugin(mobject):
    mplugin = OpenMayaMPx.MFnPlugin(mobject)
    try:
        mplugin.deregisterCommand(kPluginCmdName)
    except:
        sys.stderr.write("Failed to unregister command: %s\n" % kPluginCmdName)

这个例子是官方的 Your First Maya Python Plug-in

还有更多例子，可以参考maya目录devkit下
