Python学习笔记字典之漂亮打印pprint模块

随笔记录方便自己和同路人查阅。

#------------------------------------------------我是可耻的分割线-------------------------------------------

　　如果程序中倒入pprint模块，就可以使用pprint()和pformat()函数，它们将“漂亮打印”一个字典的字。如果

想要字典中表项的现实比print()的输出结果更干净，这就游泳了。

　　1、普通打印，示例代码1：

count = {}
message = 'It was a bright cold day in April, and the clocks were striking thirteen.'
for character in message:
    count.setdefault(character,0)
    count[character] = count[character] +1
print(count)

　　运行结果：

 

　　2、漂亮打印，示例代码：

import pprint
count = {}
message = 'It was a bright cold day in April, and the clocks were striking thirteen.'
for character in message:
    count.setdefault(character,0)
    count[character] = count[character] +1
pprint.pprint(count)

　　运行结果：

　　3、如果希望得到漂亮打印的文本作为字符串，而不是显示在屏幕上，那就调用pprint.format()，示例代码：

import pprint
count = {}
message = 'It was a bright cold day in April, and the clocks were striking thirteen.'
for character in message:
    count.setdefault(character,0)
    count[character] = count[character] +1
#pprint.pprint(count)
print(pprint.pformat(count))

　　运行结果：

　　根据运行结果可以看出，pprint.pprint(count)和print(pprint.pformat(count))是等价的
