列表:
name=[‘who‘,‘where‘,‘how‘]
1.切片:左闭右开
name[:]=name
name[0:4]=‘who‘
2.追加:
name.append(‘when‘)===>[‘who‘,‘where‘,‘how‘,‘when‘]
3.插入
name.insert(1,‘loser‘)===>[‘who‘,‘loser‘,‘where‘,‘how‘]
4.修改
name[1]=‘victor‘===>[‘who‘,‘victor‘,‘how‘]
5.删除
name.remove(1)===>name=[‘who‘,‘how‘]
name.pop(1)===>name=[‘who‘,‘how‘]
del name(‘where‘)===>name=[‘who‘,‘how‘]
6.拓展
p=[‘i‘,‘he‘,‘you‘,‘who‘]
name.extend(p)===>name=[‘who‘,‘where‘,‘how‘,‘i‘,‘he‘,‘you‘,‘who‘]
7.统计
name=[‘who‘,‘where‘,‘how‘,‘i‘,‘he‘,‘you‘,‘who‘]
name.count(‘who‘)=2
8.排序、反转(python3 中不同数据类型无法排序)
name=[‘who‘,‘where‘,‘how‘,‘i‘,‘he‘,‘you‘,‘who‘,‘1‘,‘2‘,‘3‘]
name.reverse()
name=[‘3‘, ‘2‘, ‘1‘, ‘who‘, ‘you‘, ‘he‘, ‘i‘, ‘how‘, ‘where‘, ‘who‘]
name.sort()
name=[‘1‘, ‘2‘, ‘3‘, ‘he‘, ‘how‘, ‘i‘, ‘where‘, ‘who‘, ‘who‘, ‘you‘]
9.获取下标
name=[‘who‘,‘where‘,‘how‘]
name.index(‘who‘)=0
10.拷贝
name=[‘who‘,‘where‘,‘how‘]
浅copy:
a=name.copy()
a=name[:]
a=list(name)
当有嵌套列表时,修改a会将name中嵌套列表的数据修改掉
name=[‘who‘,‘where‘,‘how‘,[‘when‘,‘here‘]]
a=name.copy()
a[1]=‘zh‘,a=[‘who‘,‘a‘,‘how‘,[‘when‘,‘here‘]],name=[‘who‘,‘where‘,‘how‘,[‘when‘,‘here‘]]
当修改嵌套内列表时,a和name都会改变
name=[‘who‘,‘where‘,‘how‘,[‘when‘,‘here‘]]
a[3][1]=‘there‘
a=[‘who‘,‘where‘,‘how‘,[‘when‘,‘there‘]]
name=[‘who‘,‘where‘,‘how‘,[‘when‘,‘there‘]]
深copy:
import copy
name=[‘who‘,‘where‘,‘how‘,[‘when‘,‘here‘]]
a=copy.deepcopy(name)
a[3][1]=‘there‘
name=[‘who‘,‘where‘,‘how‘,[‘when‘,‘here‘]]
a=[‘who‘,‘where‘,‘how‘,[‘when‘,‘there‘]]
