day③：函数式编程

def func(name): #name :形参
    print name
func(‘chenyaobin‘) #‘chenyaobin :实参‘

def func(name,age=24):
     print("my name is %s,age: %s") %(name,age)
func("chenyaobin") #age用了默认参数
func("hy","18") #指定参数
结果：
my name is chenyaobin,age: 24
my name is hy,age: 18

def func(name,age=24):
     print("my name is %s,age: %s") %(name,age)
func("chenyaobin") #age用了默认参数
func("test",30) #按顺序的指定
#func(age=30,"test") #不可以这样子，会报错
func(age=30,name="test") #不按顺序的指定
结果：
my name is chenyaobin,age: 24
my name is test,age: 30
my name is test,age: 30

# 动态参数
# 例子①：
def func(*args):
     print args

#执行方式一
func(11,22,33,44,55,66)

#执行方式二
li = [11,22,33,44,55,66]
func(*li)
结果：
(11, 22, 33, 44, 55, 66)
(11, 22, 33, 44, 55, 66)

# 动态参数
# 例子②：
def func(**kwargs):
     print kwargs
#执行方式一
func(name="yaobin",age=18)
#执行方式二
li={"name":"yaobin","age":18,‘gender‘:‘male‘}
func(**li)
结果：
{‘age‘: 18, ‘name‘: ‘yaobin‘}
{‘gender‘: ‘male‘, ‘age‘: 18, ‘name‘: ‘yaobin‘}

# 动态参数
# 例子③:
def foo1(arg1,arg2,key1=1,key2=2,*arg,**keywords):
     print "arg1 parameters is ",arg1
     print "arg2 parameters is ",arg2
     print "key1 parameter is ",key1
     print "key2 parameter is ",key2
     print "Arbitrary parameter is ", arg
     print "keywords parameter is ",keywords
foo1(2,3,4,5,456,789,a1=10,a2=20,a3=30) 
结果：
arg1 parameters is  2
arg2 parameters is  3
key1 parameter is  4
key2 parameter is  5
Arbitrary parameter is  (456, 789)
keywords parameter is  {‘a1‘: 10, ‘a3‘: 30, ‘a2‘: 20}
