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:
#------------------------------------------------------------------------------- # Name: 【记录】折腾Python中的pprint # Author: Crifan Li # # Created: 06/01/2013 # Copyright: (c) Crifan Li 2013 #------------------------------------------------------------------------------- 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。
