例子:
first with *args
args = ("two", 3,5)
test_args_kwargs(*args)
arg1: two
arg2: 3
arg3: 5
now with **kwargs:
kwargs = {"arg3": 3, "arg2": "two","arg1":5}
test_args_kwargs(**kwargs)
arg1: 5
arg2: two
arg3: 3
另外的例子:
*self._args 表示接受元组类参数;
*kwargs 表示接受字典类参数;
以下是网上的例子:
def foo(args, **kwargs):
print 'args = ', args
print 'kwargs = ', kwargs
print '---------------------------------------'
if name == 'main':
foo(1,2,3,4)
foo(a=1,b=2,c=3)
foo(1,2,3,4, a=1,b=2,c=3)
foo('a', 1, None, a=1, b='2', c=3)
输出结果如下:
args = (1, 2, 3, 4)
kwargs = {}
args = ()
kwargs = {'a': 1, 'c': 3, 'b': 2}
args = (1, 2, 3, 4)
kwargs = {'a': 1, 'c': 3, 'b': 2}
args = ('a', 1, None)
kwargs = {'a': 1, 'c': 3, 'b': '2'}
