Learning Python

Data Structures --Python

Python貌似有很多内置的数据类型

看的几本书都不完全一样,但也差不多

  • numbers                数值
  • strings                   字符串
  • lists                       列表
  • tuples                    元组
  • dictionaries            字典

看的有点混乱

不过基本都有详细讲 lists,tuples,dictionaries三种

lists:

>>>a=[3.31,534,[54,'cat']'eggs']
>>>a
a=[3.31,534,[54,'cat']'eggs']

 

tuples:

>>>b=56,4.43,'dog'
>>>b
(56,4,43,'dog')

 

dictionaries:

>>>dict={'jack':342,'sape':'ax'}
{'jack':342,'sape':'ax'}

 

imutable basic types      不可变基本类型

           numbers,strings,tuples  (数值,字符串,元组)

mutable basic types

           lists,dictionaries,and most other types   (字典,链表和其它的)

 

还有好多详细的记不太清了,赶紧复习一下...
