python 列表删除元素 
python 删除元素的几种方式
方式一:使用del方法
>>> names=['alice','beth','cecil','dee-dee','earl'] >>> names ['alice', 'beth', 'cecil', 'dee-dee', 'earl'] >>> del names[2] >>> names ['alice', 'beth', 'dee-dee', 'earl'] >>>
>>> numbers=['a', 'b', 'c', 'd'] >>> numbers ['a', 'b', 'c', 'd'] >>> del numbers[1:3] >>> numbers ['a', 'd']
方式二:分片赋值
>>> numbers=['a', 'b', 'c', 'd'] >>> numbers ['a', 'b', 'c', 'd'] >>> numbers[1:3]=[] >>> numbers ['a', 'd']
