1.创建列表类型数据并给其赋值
>>> aList = [123,'abc',4.56,['inner','list'],7-9j]
>>> aList
[123, 'abc', 4.56, ['inner', 'list'], (7-9j)]
>>> list('ABC')
['A', 'B', 'C']
2.访问列表中的值
>>> aList[0] 123 >>> aList[1:4] ['abc', 4.56, ['inner', 'list']] >>> aList[:3] [123, 'abc', 4.56] >>> aList[3][1] 'list'
3.如何更新列表
>>> aList[2]='ABC'
>>> aList
[123, 'abc', 'ABC', ['inner', 'list'], (7-9j)]
>>> aList.append("Hello Word")
>>> aList
[123, 'abc', 'ABC', ['inner', 'list'], (7-9j), 'Hello Word']
4.删除列表中的元素或者列表本身
>>> del aList[1] >>> aList [123, 'ABC', ['inner', 'list'], (7-9j), 'Hello Word'] >>> aList.remove(123) >>> aList ['ABC', ['inner', 'list'], (7-9j), 'Hello Word']
>>> del aList
5.标准类型操作符
列表比较操作的时候，是两个列表的元素分别比较，直到有一方的元素胜出
6.序列类型操作符
<1>切片（[]和[:]）
>>> aList [123, 'abc', 'ABC', ['inner', 'list'], (7-9j), 'Hello Word'] >>> aList[-2:-1] [(7-9j)]
>>> aList[2:-1]
['ABC', ['inner', 'list'], (7-9j)]
<2>成员关系操作（in,not in）
输出的是True或者False
<3>连接操作符（+）
>>> aList=[1,2,3,4] >>> bList=['A','B','C','D'] >>> cList = aList+bList >>> cList [1, 2, 3, 4, 'A', 'B', 'C', 'D']
<4>重复操作符（*）
>>> aList * 2 [1, 2, 3, 4, 1, 2, 3, 4]
7.标准类型函数cmp()
比较的规则P140
8.序列类型函数
<1>len()——对列表和元组返回的是列表或者元组的元素个数
<2>max()和min()——比较大小
<3>sorted()和reversed()——
>>> bList ['A', 'B', 'C', 'D'] >>> for t in reversed(bList): ... print t ... D C B A >>> bList=['D','C','B','A'] >>> sorted(bList) ['A', 'B', 'C', 'D']
<4>enumerate()和zip()——
['A', 'B', 'C', 'D']
>>> for i,t in enumerate(bList):
... print i,t
...
0 A
1 B
2 C
3 D
>>> aList
[1, 2, 3, 4]
>>> bList
['A', 'B', 'C', 'D']
>>> for i,j in zip(aList,bList):
... print ('%s %s' % (i,j)).title()
...
1 A
2 B
3 C
4 D
<5>sum()
>>> aList [1, 2, 3, 4] >>> sum(aList) 10
<6>list()和tuple()——用于列表和元组之间的转换
9.列表类型的内建函数——P142
>>> dir(aList)
['__add__', '__class__', '__contains__', '__delattr__', '__delitem__', '__delslice__', '__doc__', '__eq__', '__format__', '__ge__', '__getattribute__', '__getitem__', '__getslice__', '__gt__', '__hash__', '__iadd__', '__imul__', '__init__', '__iter__', '__le__', '__len__', '__lt__', '__mul__', '__ne__', '__new__', '__reduce__', '__reduce_ex__', '__repr__', '__reversed__', '__rmul__', '__setattr__', '__setitem__', '__setslice__', '__sizeof__', '__str__', '__subclasshook__', 'append', 'count', 'extend', 'index', 'insert', 'pop', 'remove', 'reverse', 'sort']
>>> aList
[1, 2, 3, 4]
>>> aList.append('A')
>>> aList
[1, 2, 3, 4, 'A']
>>> aList.count('A')
1
>>> aList.insert(1,1.5)
>>> aList
[1, 1.5, 2, 3, 4, 'A']
>>> 'A' in aList
True
>>> aList.index(1.5)
1
>>> aList.sort()
>>> aList
[1, 1.5, 2, 3, 4, 'A']
>>> aList.reverse() #没有返回值的函数会直接改变对象的值
>>> aList
['A', 4, 3, 2, 1.5, 1]
>>> bList.extend(aList)
>>> bList
['A', 'B', 'C', 'D', 'A', 4, 3, 2, 1.5, 1]
10.append和extend
