---------------------------------------------------------------------------------------------'''
6.count():用于统计某个元素在列表中出现的次数

1
---------------------------------------------------------------------------------------------'''
7.index():用于从列表中找出某个值第一个匹配项的索引位置
'''
l=['11','222','aaa','bbb','222','cc']
print l.index('222')
print l.index('cc')--------------------------------------------1
5
---------------------------------------------------------------------------------------------'''
8.expend():函数用于在列表末尾一次性追加另一个序列中的多个值（用新列表扩展原来的列表）。
'''
l1=['11','22','33']
l2=['aa','bb','cc']
l1.extend(l2)
print l1--------------------------------------------['11', '22', '33', 'aa', 'bb', 'cc']
---------------------------------------------------------------------------------------------'''
9.insert(obj,str):指定位置插入指定对象
'''
l=['11','22','33','44']
l.insert(1,['aa','bb','cc'])
print l--------------------------------------------['11', ['aa', 'bb', 'cc'], '22', '33', '44']---------------------------------------------------------------------------------------------'''
10.pop([index=-1]):移除列表中的一个元素（默认为最后一个元素），可选择元素
'''
l=['11','22','33','44']
print l
l.pop()
print l
l.pop(1)
print l-------------------------------------------- ['11', '22', '33', '44']
['11', '22', '33']
['11', '33']
---------------------------------------------------------------------------------------------'''
11.remove(obj):用于移除列表中某个值的第一个匹配项。
'''
l=['11','222','aaa','bbb','222','cc']
l.remove('222')
print l--------------------------------------------['11', 'aaa', 'bbb', '222', 'cc']

12.reverse()：反向列表中的元素
'''
l=['11','22','33','44']
l.reverse()
print l--------------------------------------------['44', '33', '22', '11']
---------------------------------------------------------------------------------------------'''
13.sort()：用于对原列表进行排序（默认升序），如果指定参数，则使用比较函数指定的比较函数。
reverse -- 排序规则，reverse = True 降序， reverse = False 升序（默认）。
'''
l=['11','222','aaa','bbb','222','cc']
l.sort()
print l
l=['11','222','aaa','bbb','222','cc']
l.sort(reverse=True)
