Question

这是我正在研究的python脚本，我是pyhton脚本的新手，这是我们在学校学习的东西，我需要一些帮助。这是我不断得到的错误，我不明白无效的语法是什么。感谢您的任何帮助。 “import maya.cmds as cmds”，这是我正在处理的程序的一部分，

        #Error: line 1: invalid syntax
        #   File "<maya console>", line 27
        #     transformInScene = cmds.ls(type='transform')
        #                    ^
        # SyntaxError: invalid syntax #

cmds.file（新=真，力=真）

        import maya.cmds as cmds
        def changeXtransformValue(myList, percentage=1.0):
            """

这是学校项目的一部分，在修复缩进后，我似乎无法找到问题

Answer 1

以上一行......

               cmds.xform(sphere1, t = (0.5, 0.5, 0.5)

缺少xform来电的右括号。

Answer 2

你在“cmds.xform（sphere1，t =（0.5,0.5,0.5）”

行忘记了一个'）'

看你用两个'（'但只有一个'）'

最后添加一个：

替换cmds.xform（sphere1，t =（0.5,0.5,0.5）同 cmds.xform（sphere1，t =（0.5,0.5,0.5））
