>>> x = ['a','b','c','d','e']
>>> y = [1,2,3,4,5]
>>> for i,j in zip(x,y):
		print(i,j)	
a 1
b 2
c 3
d 4
e 5

for i in sorted(sor):排序
for i in sorted(set(sor)): 排序去重
for i in reversed(range(len(lis))):倒序

查询格式为:
list[起始位置:结束位置:步长]
list特点为顾头不顾腚，包含开头不包含结尾
步长默认为正序，步长1；可修改
如：1，2，3......
步长也可为负数，则查询结果为倒序
如：-1，-2，-3.....
正序时，起始和结束也为正序，起始在前结束在后
倒序时，起始和结束也需为倒序，起始在后结束在前

倒序+步长
lis1 = ['a','b','c','d','e','f']
>>> lis1[::-1]
['f', 'e', 'd', 'c', 'b', 'a']
>>> lis1[-1:0:-1]
['f', 'e', 'd', 'c', 'b']
>>> lis1[::2]
['a', 'c', 'e']
添加元素
lis1.append("g")
>>> lis1
['a', 'b', 'c', 'd', 'e', 'f', 'g']
删除元素
>>> li = lis1.pop()
>>> li
'g'
>>> lis1
['a', 'b', 'c', 'd', 'e', 'f']
插入元素
>>> lis1.insert(0,"y")
>>> lis1
['y', 'a', 'b', 'c', 'd', 'e', 'f']
出现次数+出现位置
>>> lis2 = ['a','b','a','a','b','c']
>>> lis2.count('a')
3
>>> lis2.count('b')
2
>>> lis2.index("b")
1
>>> lis2.index('b',2)
4
>>> lis2.index('c')
5
排序+倒序
>>> lis3 = [3,5,1,8,2,4,6,3]
>>> lis3.sort()
>>> lis3
[1, 2, 3, 3, 4, 5, 6, 8]
>>> lis3.sort(reverse=-1)
>>> lis3
[8, 6, 5, 4, 3, 3, 2, 1]
扩展列表
>>> lis3[len(lis3):]=["a","b","c"]
>>> lis3
[8, 6, 5, 4, 3, 3, 2, 1, 'a', 'b', 'c']
>>> lis3.extend(['d','e','f'])
>>> lis3
[8, 6, 5, 4, 3, 3, 2, 1, 'a', 'b', 'c', 'd', 'e', 'f']
去重
>>> l1 = ['b','c','d','b','c','a','a']
>>> l2 = list(set(l1))
>>> l2
['c', 'b', 'a', 'd']
>>> l2=list(set(l1))
>>> l2.sort(key=l1.index)#去重后顺序不变
>>> l2
['b', 'c', 'd', 'a']
>>> l1
['b', 'c', 'd', 'b', 'c', 'a', 'a']
>>> l2=list({}.fromkeys(l1).keys())
>>> l2
['b', 'c', 'd', 'a']
>>> l1
['b', 'c', 'd', 'b', 'c', 'a', 'a']
>>> l2=[]
>>> for i in l1:
	if not i in l2:
		l2.append(i)
>>> l2
['b', 'c', 'd', 'a']
>>> l1
['b', 'c', 'd', 'b', 'c', 'a', 'a']
>>> l2 = []
>>> [l2.append(i) for i in l1 if not i in l2]
[None, None, None, None]
>>> l2
['b', 'c', 'd', 'a']


import copy
person = ['name',['a',100]]
p1 = copy.copy(person)
p2 = person[:]
p3 = list(person)
浅copy创建联合帐号
p1 = person[:]
p2 = person[:]
p1[0] = 'A'
P2[0] = 'B'
p[1][1] = 50
print(p1,p2)

元组turple 只有count 和 index
