集合
collections是Python内建的一个集合模块，提供了许多有用的集合类。
namedtuple
我们知道tuple可以表示不变集合，例如，一个点的二维坐标就可以表示成：
'''
p = (1, 2)
'''
但是，看到(1, 2)，很难看出这个tuple是用来表示一个坐标的。
定义一个class又小题大做了，这时，namedtuple就派上了用场：
'''
from collections import namedtuple
Point = namedtuple('Point', ['x', 'y'])
p = Point(1, 2)
print(p.x)

'''
匿名函数
当我们在传入函数时，有些时候，不需要显式地定义函数，直接传入匿名函数更方便。
在Python中，对匿名函数提供了有限支持。还是以map()函数为例，计算f(x)=x2时，除了定义一个f(x)的函数外，还可以直接传入匿名函数：
'''
l = list(map(lambda x: x * x, [1, 2, 3, 4, 5, 6, 7, 8, 9]))
print(l)
# [1, 4, 9, 16, 25, 36, 49, 64, 81]
'''
通过对比可以看出，匿名函数lambda x: x * x实际上就是
def f(x):
return x * x
'... |
'''
调用函数
Python内置了很多有用的函数，我们可以直接调用。
要调用一个函数，需要知道函数的名称和参数，比如求绝对值的函数abs，只有一个参数。可以直接从Python的官方网站查看文档：
函数大全：http://docs.python.org/3/library/functions.html
基础函数：abs max
数据类型转换：int('str') float('str') str(number) bool(1) bool('')
'''
# tips:也可以在交互式命令行通过help(abs)查看abs函数的帮助信息。
help(abs)
# abs(...)
# ... |
'''
排序算法
排序也是在程序中经常用到的算法。无论使用冒泡排序还是快速排序，排序的核心是比较两个元素的大小。
如果是数字，我们可以直接比较，但如果是字符串或者两个dict呢？直接比较数学上的大小是没有意义的，因此，比较的过程必须通过函数抽象出来。
'''
print(sorted([36, -5, 1, 22]))
# [-5, 1, 22, 36]
'''
此外，sorted()函数也是一个高阶函数，它还可以接收一个key函数来实现自定义的排序，例如按绝对值大小排序：
'''
print(sorted([36, -5, 1, 22], key=abs))
# [1, -5, 22, 36]
'''
