python - 格式化字典打印输出

Question

我有一个名为 d 的字典，其中存储了多个列表。如果我打印字典，我会得到难以阅读的输出:

 {'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]}

我只想在新行中打印每个 Patch 和相应的数据:

 {'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], 

在看到 this answer : 中的建议后，我尝试了 pprint

 pprint.pprint(d, width=1)

我明白了:

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

我在这里错过了什么？

Answer 1

只需传入足够大的宽度以容纳 dict 中的每个值:

>>> 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],
