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']
