### 匿名函数
#Python中，对匿名函数提供了有限支持
>>> list(map(lambda x: x * x, [1, 2, 3, 4, 5, 6, 7, 8, 9]))
#[1, 4, 9, 16, 25, 36, 49, 64, 81]
## 关键字lambda表示匿名函数，冒号前面的x表示函数参数
## 匿名函数有个限制，就是只能有一个表达式，不用写return，返回值就是该表达式的结果
## 匿名函数也是一个函数对象，也可以把匿名函数赋值给一个变量，再利用变量来调用该函数：
>>> f = lambda x: x * x
>>> f
# <function <lambda> at 0x101c6ef28>... |
### 函数的参数
## Python的函数定义灵活度非常大。
## 除了正常定义的必选参数外，还可以使用默认参数、可变参数和关键字参数
# 位置函数
def power(x):
return x * x
# 要计算x4、x5…，就要把power(x)修改为power(x, n)，用来计算x^n
def power(x, n):
s = 1
while n > 0:
n = n - 1
s = s * x
return s
## x和n，这两个参数都是位置参数，调用函数时，传入的两个值按照位置顺序*依次*赋给参数x和n
