默认参数必须放在最后面，否则会报：

SyntaxError: non-default argument follows default argument

# 可写函数说明

def printinfo( age=35,name):   # 默认参数不在最后，会报错

   "打印任何传入的字符串"

   print("名字: ", name)

   print("年龄: ", age)

   return

def(**kwargs) 把N个关键字参数转化为字典:

>>>def func(country,province,**kwargs):

...     print(country,province,kwargs)

... 

>>> func("China","Sichuan",city ="Chengdu", section ="JingJiang")

ChinaSichuan{'city':'Chengdu','section':'JingJiang'}

>>>
