零基础学python-8.2 列表的基本操作、迭代和解析

基本操作：使用+和*

>>> a='http://blog.youkuaiyun.com/raylee2007'
>>> aList=['123',123,123.0]
>>> bList=['dd',a,['123','aaa']]
>>> aList+bList
['123', 123, 123.0, 'dd', 'http://blog.youkuaiyun.com/raylee2007', ['123', 'aaa']]
>>> 

迭代：

>>> 3 in [1,2,3]
True
>>> for x in range(5):print(x)

0
1
2
3
4
>>> 

解析：

>>> result=[x*3 for x in 'my date']
>>> result
['mmm', 'yyy', '   ', 'ddd', 'aaa', 'ttt', 'eee']
>>> 

就说到这里，谢谢大家
