help
在交互模式下，help函數(shù)是獲取文檔的好幫手，使用非常簡單。
>>> 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__是每個(gè)對象都有的屬性，其存放了對象文檔。

離線文檔
安裝Python時(shí)會自帶一個(gè)chm格式的離線文檔Python documention，該文檔的信息比較全。
離線模塊文檔
Python針對模塊還有一個(gè)單獨(dú)的文檔，該文檔在瀏覽器中查看。
在線文檔
在瀏覽器打開https://docs.python.org/3.4/
