Python學習筆記字典之漂亮打印pprint模塊

隨筆記錄方便自己和同路人查閱。

#------------------------------------------------我是可恥的分割線-------------------------------------------

　　如果程序中倒入pprint模塊，就可以使用pprint()和pformat()函數，它們將“漂亮打印”一個字典的字。如果

想要字典中表項的現實比print()的輸出結果更干凈，這就游泳了。

　　1、普通打印，示例代碼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)

　　運行結果：

 

　　2、漂亮打印，示例代碼：

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)

　　運行結果：

　　3、如果希望得到漂亮打印的文本作為字符串，而不是顯示在屏幕上，那就調用pprint.format()，示例代碼：

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))

　　運行結果：

　　根據運行結果可以看出，pprint.pprint(count)和print(pprint.pformat(count))是等價的
