格式化字典打印輸出

我有一個名爲d的字典，它有幾個存儲在其中的列表。如果我打印的字典我得到這個難讀輸出：格式化字典打印輸出

{'Patch(0,8)': [28, 56, 75], 'Patch(0,6)': [1, 11, 17, 19, 20, 23, 28, 30, 44, 45, 49, 56, 60, 63, 75, 81, 91, 99], 
'Patch(4,0)': [2, 5, 6, 8, 19, 22, 23, 27, 31, 34, 35, 36, 41, 45, 51, 52, 53, 55, 56, 59, 60, 61, 62, 64, 66, 67, 68, 70, 73, 75, 76, 77, 79, 85, 87, 91, 94, 96], 
'Patch(4,6)': [19, 23, 45, 56, 60, 75, 91], 'Patch(0,0)': [0, 1, 2, 3, 4, 5, 6, 7, 8, 9, 
    10, 11, 12, 13, 14, 15, 16, 17, 18, 19, 20, 21, 22, 23, 24, 25, 26, 27, 28, 29, 30, 31, 32, 33, 34, 35, 36, 37, 38, 39, 40, 41, 42, 43, 44, 45, 46, 47, 48, 49, 50, 51, 52, 53, 54, 55, 56, 
    57, 58, 59, 60, 61, 62, 63, 64, 65, 66, 67, 68, 69, 70, 71, 72, 73, 74, 75, 76, 77, 78, 79, 80, 81, 82, 83, 84, 85, 86, 87, 88, 89, 90, 91, 92, 93, 94, 95, 96, 97, 98, 99], 'Patch(8,0)': [2, 22, 23, 27, 34, 52 
, 55, 60, 85], 'Patch(0,2)': [0, 1, 2, 3, 4, 6, 7, 10, 11, 13, 15, 16, 17, 18, 19, 20, 22, 23, 25, 26, 28, 29, 30, 32, 34, 36, 37, 38, 40, 43, 44, 45, 46, 47, 
    49, 50, 51, 52, 53, 54, 56, 58, 59, 60, 61, 62, 63, 64, 66, 70, 71, 74, 75, 76, 77, 78, 80, 81, 83, 85, 90, 91, 92, 93, 94, 96, 98, 99], 'Patch(2,8)': [28, 56, 75], 'Patch(4,8)': [56, 75]}

我只是想在一個新行打印每個Patch和相應的數據：

{'Patch(0,8)': [28, 56, 75], 
    'Patch(0,6)': [1, 11, 17, 19, 20, 23, 28, 30, 44, 45, 49, 56, 60, 63, 75, 81, 91, 99],

我看到的建議後試圖pprintthis answer :

pprint.pprint(d, width=1)

我得到這個：

{'Patch(0,8)': [28, 
       56, 
       75], and so on

我在這裏錯過了什麼？

只是通過在寬度是大到足以容納在dict每個值：

>>> pprint.pprint(d, width=1000) 
{'Patch(0,0)': [0, 1, 2, 3, 4, 5, 6, 7, 8, 9, 10, 11, 12, 13, 14, 15, 16, 17, 18, 19, 20, 21, 22, 23, 24, 25, 26, 27, 28, 29, 30, 31, 32, 33, 34, 35, 36, 37, 38, 39, 40, 41, 42, 43, 44, 45, 46, 47, 48, 49, 50, 51, 52, 53, 54, 55, 56, 57, 58, 59, 60, 61, 62, 63, 64, 65, 66, 67, 68, 69, 70, 71, 72, 73, 74, 75, 76, 77, 78, 79, 80, 81, 82, 83, 84, 85, 86, 87, 88, 89, 90, 91, 92, 93, 94, 95, 96, 97, 98, 99], 
'Patch(0,2)': [0, 1, 2, 3, 4, 6, 7, 10, 11, 13, 15, 16, 17, 18, 19, 20, 22, 23, 25, 26, 28, 29, 30, 32, 34, 36, 37, 38, 40, 43, 44, 45, 46, 47, 49, 50, 51, 52, 53, 54, 56, 58, 59, 60, 61, 62, 63, 64, 66, 70, 71, 74, 75, 76, 77, 78, 80, 81, 83, 85, 90, 91, 92, 93, 94, 96, 98, 99],

'Patch(0,8)': [28, 56, 75], 
'Patch(2,8)': [28, 56, 75], 
'Patch(4,0)': [2, 5, 6, 8, 19, 22, 23, 27, 31, 34, 35, 36, 41, 45, 51, 52, 53, 55, 56, 59, 60, 61, 62, 64, 66, 67, 68, 70, 73, 75, 76, 77, 79, 85, 87, 91, 94, 96],

你可以把它變成一個簡單的循環來打印它。看官方文檔dict.iteritems。

for key, value in d.iteritems(): 
    print key + " - " + str(value)

FWIW，在Python 3'dict.iteritems'不存在。相反，'dict.items'現在返回一個迭代器，所以你可以在必須在兩個版本上運行的代碼中使用'dict.items'（當然在Python 2中它將返回一個列表而不是迭代器，所以它'可能會使用更多的RAM）。 –

我通常會打印作爲JSON的字典給它結構和格式我可以很容易地閱讀。

import json 
json.dumps(dict(a=1, b=2), indent=2)

但是，這並不是OP想要的，它將列表項放在不同的行上。使用JSON來顯示字典_can_方便，但它有各種限制：非字符串鍵被轉換爲字符串; 'None'，'True'和'False'被轉換爲JSON等價物。 –
