1.背景

看到这里提到了pprint。 
打算去试试.

2.pprint简介

找到在线官网解释：

pprint—Dataprettyprinter 

就是一个，方便大家打印一些，相对复杂的变量的好东西。

3.使用pprint

去写点代码试试。


代码：

复制代码代码如下:

importpprint;
importre;

defpprintDemo():
   varsList=[
       [1,2,3],
       ["ab","c","def"],
       re.compile("\w+"),
       ("123","abc"),
       {
           "key1":"value1",
           "key2":"value2",
       },
   ];

   forvalueinvarsList:
       printvalue;

   print"-"*80;

   pp=pprint.PrettyPrinter(indent=4);
   forvalueinvarsList:
       pp.pprint(value);

   print"="*80;
   stuff=["spam","eggs","lumberjack","knights","ni"];
   stuff.insert(0,stuff[:]);
   printstuff;
   print"-"*80;
   pp.pprint(stuff)

if__name__=="__main__":
   pprintDemo();

效果：

复制代码代码如下:


[1,2,3]
["ab","c","def"]
<_sre.SRE_Patternobjectat0x00000000030DD378>
("123","abc")
{"key2":"value2","key1":"value1"}
--------------------------------------------------------------------------------
[1,2,3]
["ab","c","def"]
<_sre.SRE_Patternobjectat0x00000000030DD378>
("123","abc")
{  "key1":"value1","key2":"value2"}
================================================================================
[["spam","eggs","lumberjack","knights","ni"],"spam","eggs","lumberjack","knights","ni"]
--------------------------------------------------------------------------------
[  ["spam","eggs","lumberjack","knights","ni"],
   "spam",
   "eggs",
   "lumberjack",
   "knights",
   "ni"]

4.总结

pprint，有点意思。

以后可以用在代码调试过程中。
