Python3 函数参数

 # # 常规参数
 # def jiafa(a,b):
 #     print(a+b)
 #
 # jiafa(5,6)
 #
 #
 # def xinxi(name,location,sex='male'):    # 默认参数在其他参数的后面
 #     print('姓名：%s'%name)
 #     print('性别：%s'%sex)
 #     print('故乡：%s'%location)
 #
 #
 # xinxi('bob','shanxi')
 #
 # # 可变长参数
 # def add(*jiafa):    # *之后跟一个元组，名字随意，一般写args(无命名参数)
 #     print(jiafa)
 #     sum = 0
 #     for i in jiafa:
 #         sum += i
 #     print(sum)
 # add(5,5,5)
 #
 # def informations(**info):   # **之后跟一个字典，名字随意，一般写kwargs(有命名参数)
 #
 #     for i in info:  # i是键，info是值
 #         print('%s:%s'%(i,info[i]))
 # informations(name = 'Lily',age = 18,sex = 'female',job = 'policewoman',location ='beijing')
 #
 # def test(*a,**b):
 #     print(a,b)
 # test('asd',2,22,['asd',1],(1,2,3,4,5),name = 'bob')

 关于不定长参数的位置 *agrs 放在左边， **kwargs 放在右边
 默认值加不定长参数的左边
 顺序：关键字参数，默认值参数，*args，**kwargs
