parse and evaluate a Python def statement
The DefineFunction command sends the given string, def, to be executed by a Python interpreter.
This command is the same as calling Python:-EvalString with the output=none option.
This command always returns NULL. A subsequent EvalString or GetVariable command must be used if you want to get a reference to the procedure that was defined.
This function is part of the Python package, so it can be used in the short form DefineFunction(..) only after executing the command with(Python). However, it can always be accessed through the long form of the command by using Python[DefineFunction](..).
DefineFunction⁡def mysum(a,b): return a+b
MySum≔<Python object: <function mysum at 0x7fb5055523a0>>
Indentation matters; use \n for newlines and spaces or \t for tabs
DefineFunction⁡def flatten(lst):\n\treturn sum( ([x] if not isinstance(x, list) else flatten(x)\n\tfor x in lst),  ):
The Python[DefineFunction] command was introduced in Maple 2018.
