Dear 笹原康央, This sounds interesting. The assignment could be done e.g., like this. ```python def assign(variables): return f''' for _variable, _value in (lambda {variables}: locals())( *_values, **_assignments ).items(): exec(f'{{_variable}} = _value') ''' def name_update(_namespace, /, *_values, **_assignments): return _namespace.update(locals()) name_update(globals(), 1, 2, *[3,4], **{"b":4}, c=4 ) exec(assign( "a, *args, b, **kwargs" )) def f(): name_update(locals(), 1, 2, *[3,4], **{"b":4}, c=4 ) exec(assign( "a, *args, b, **kwargs" )) return locals() ``` This is certainly much more writing than an assignment statement. (It works also with global and nonlocal variables. One should remove the side effects, which shouldn't be hard with a context manager for instance. The code is not for assignment to the variable "_variable", "_value", or "exec". I haven't thought how to make assignment to any variable possible. Finally, the necessity to call exec requires care.)
