python文档怎么看
查看文档是一个程序员的基本功，这里简单介绍几种查看Python文档的方法，下面以struct模块为例。
help
在交互模式下，help函数是获取文档的好帮手，使用非常简单。
>>> import struct>>> help(struct)
Help on module struct:
NAME
struct
DESCRIPTION
Functions to convert between Python values and C structs.
Python bytes objects are used to hold the data representing the C struct
and also as format strings (explained below) to describe the layout of data
in the C struct.
The optional first format char indicates byte order, size and alignment:
@: native order, size & alignment (default)
=: native order, std. size & alignment
<: little-endian, std. size & alignment
>: big-endian, std. size & alignment
!: same as >
The remaining chars indicate types of args and must match exactly;
these can be preceded by a decimal repeat count:
x: pad byte (no data); c:char; b:signed byte; B:unsigned byte;
?: _Bool (requires C99; if not available, char is used instead)
h:short; H:unsigned short; i:int; I:unsigned int;
__doc__
__doc__是每个对象都有的属性，其存放了对象文档。
>>> import struct>>> struct.__doc__

离线文档
安装Python时会自带一个chm格式的离线文档Python documention，该文档的信息比较全。
离线模块文档
Python针对模块还有一个单独的文档，该文档在浏览器中查看。
在线文档
在浏览器打开https://docs.python.org/3.4/
