python里面有两个比较有特色的函数入参,*和**,按照习惯,一般命名为:
def func(*args, **kwargs):
pass
<pre name="code" class="python">def func_a(**kwargs):
print kwargs
a = {"key": "value"}
func_a(a) #func_a() takes exactly 0 arguments (1 given)
func_a(*a) #func_a() takes exactly 0 arguments (1 given)
func_a(**a) #正常输出
def func_b(*args, **kwargs):
print args
print kwargs
func_b(a)
#result
({'key': 'value'},)
{}
func_b(*a)
#result
('key',)
{}
func_b(**a)
#result
()
{'key': 'value'}
func_b(test="hello", **a)
#result
()
{'test':'hello', 'key':'value'}原文地址:http://blog.csdn.net/xiaowangwindow/article/details/40819111
