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.
