# 可変長引数（tuple)
>>> def func(*v):
...     print v
...
>>> func(1)
(1,)
>>> func(1, "ABC", True)
(1, 'ABC', True)

# 可変長引数（dict)
>>> def func(**v):
...     print v
...
>>> func(1)
Traceback (most recent call last):
  File "<stdin>", line 1, in <module>
TypeError: func() takes exactly 0 arguments (1 given)
>>> func(a=1)
{'a': 1}
>>> func(a=1, b="ABC", c=True)
{'a': 1, 'c': True, 'b': 'ABC'}
