python学习笔记02 列表qlist提供的一系列应用函数如append，insert，index，remove的用法及代码实现

1、mylist.append

>>> mylist=[1024,3,True,6.5]
>>> mylist.append(False)
>>> mylist
[1024, 3, True, 6.5, False]
>>>

2、mylist.insert

>>> mylist.insert(2,5)
>>> mylist
[1024, 3, 5, True, 6.5, False]

完整代码如下：

3、mylist.pop()

>>> print(mylist.pop())
False
>>> mylist
[1024, 3, 5, True, 6.5]
>>> print(mylist.pop())
6.5
>>> print(mylist)
[1024, 3, 5, True]
>>> print(mylist.pop(0))
1024
>>> print(mylist)
[3, 5, True]

4、mylist.sort()
>>> mylist.append(1024)
>>> mylist.append(4)
>>> mylist
[3, 5, True, 1024, 4]
>>> mylist.sort()
>>> mylist
[True, 3, 4, 5, 1024]
>>> mylist.append(False)
>>> mylist
[True, 3, 4, 5, 1024, False]
>>> mylist.sort()
>>> mylist
[False, True, 3, 4, 5, 1024]

5、mylist.reverse()
>>> mylist.reverse()
>>> mylist
[1024, 5, 4, 3, True, False]

6、mylist.count()
>>> print(mylist.count(5))
1
>>> mylist
[1024, 5, 4, 3, True, False]
>>> print(mylist.count(1024))
1
>>> mylist
[1024, 5, 4, 3, True, False]
>>> print(mylist.count(1024))
1
>>> print(mylist.count(5))
1
>>> mylist.append(5)
>>> mylist.append(5)
>>> mylist.append(5)
>>> print(mylist.count(5))
4

7、mylist.index()
>>> print(mylist.index(1024))
0
>>> print(mylist.index(5))
1

8、mylist.remove()
>>> mylist.remove(5)
>>> mylist
[1024, 4, 3, True, False, 5, 5, 5]
>>> mylist.remove(5)
>>> mylist
[1024, 4, 3, True, False, 5, 5]
>>> mylist.remove(5)
>>> mylist
[1024, 4, 3, True, False, 5]

9、del mylist
>>> del mylist[0]
>>> mylist
[4, 3, True, False, 5]
