Current limitations

• For this release of Python in Maya, fixed arguments to Maya commands (for example, the x, y and z values for maya.cmds.move()) must be passed as individual arguments and cannot be packed into a tuple.
• Flag names or short forms of flags in Maya commands that are reserved words in Python have been removed from the Maya Python command syntax. For example:

  “is” is a reserved keyword in Python, and is is not a valid short form flag name. Only the long form of the flag is valid (for example, internalSet for the addAttr command).

• “break” is a reserved keyword in Python, and is not a valid long form flag. Only the short form of the flag is valid (for example, b for the uvLink and lightlink commands).

• Stacktracing (in the Script Editor, History > Show Stack Trace) only works for MEL. The stackTrace command was created for MEL to provide what Python does by default.
• Executing single Python commands echoes results to the Script editor, but executing several Python commands in the Script editor does not. This is a property of embedded Python.

  To see the returned results, you must explicitly print them.
