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 ― Data pretty printer
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:

import pprint;
import re;
def pprintDemo():
varsList = [
[1, 2, 3],
["ab", "c", "def"],
re.compile("\w+"),
("123", "abc"),
{
"key1":"value1",
"key2":"value2",
},
];
for value in varsList:
print value;
print "-"*80;
pp = pprint.PrettyPrinter(indent=4);
for value in varsList:
pp.pprint(value);
print "="*80;
stuff = ['spam', 'eggs', 'lumberjack', 'knights', 'ni'];
stuff.insert(0, stuff[:]);
print stuff;
print "-"*80;
pp.pprint(stuff)
if __name__ == '__main__':
pprintDemo();
效果:
[1, 2, 3]
['ab', 'c', 'def']
<_sre.SRE_Pattern object at 0x00000000030DD378>
('123', 'abc')
{'key2': 'value2', 'key1': 'value1'}
--------------------------------------------------------------------------------
[1, 2, 3]
['ab', 'c', 'def']
<_sre.SRE_Pattern object at 0x00000000030DD378>
('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。
