Question

我有以下列表：

import json
import pprint

scoring_dictionary=[{'IMEI': '867',
  'Timestamp': '2020-07-02 13-29-24',
  'RAG': 'G',
  'Probability': 0.12},
 {'IMEI': '430',
  'Timestamp': '2020-07-02 13-29-24',
  'RAG': 'G',
  'Probability': 0.12},
 {'IMEI': '658',
  'Timestamp': '2020-07-02 13-29-24',
  'RAG': 'G',
  'Probability': 0.12},
 {'IMEI': '157',
  'Timestamp': '2020-07-02 13-29-24',
  'RAG': 'G',
  'Probability': 0.12},
 {'IMEI': '521',
  'Timestamp': '2020-07-02 13-29-24',
  'RAG': 'G',
  'Probability': 0.12}]

我想在单元格的标准输出中漂亮地打印出来。在网上遇到类似问题后看到了这段代码，

print("The list of dictionaries per scored asset id: {0}".format(json.dumps(json.loads(scoring_dictionary), indent=4)))

但是输出仍然很差

"The list of dictionaries per scored asset id: [{'IMEI': '867', 'Timestamp': '2020-07-02 13-29-24', 'RAG': 'G', 'Probability': 0.12}, {'IMEI': '430', 'Timestamp': '2020-07-02 13-29-24', 'RAG': 'G', 'Probability': 0.12}...]" # a straight text of string without intends

除了字典列表之外，我还想打印一个看起来像这样的字典：

{'failed_devices': ['334', '897', '485'], 'partially_succeeded_devices': ['867', '430', '658', '157', '521'], 'total_failures': 705, 'total_partially_succeeded': 268, 'total_succeeded': 26, 'total': 999, 'timestamp': '2020-07-02 13-29-24', 'failures_threshold': 0.1, 'failed_percentage_out_of_total': 0.7057057057057057}

我想用与上面的词典列表相同的精确方式打印它。

[更新] 这比pprint更好。感谢所有答案。感谢您的关注。

print("The list of sotred metrics depicting the complete batch scoring execution: {0}".format(json.dumps(scoring_dictionary, indent=2)))

在此先感谢您的帮助。

对于更漂亮的打印，您可以签出pprint：

import pprint 
pprint.pprint(data)


pprint.pprint(data)

[{'IMEI': '867',
  'Probability': 0.12,
  'RAG': 'G',
  'Timestamp': '2020-07-02 13-29-24'},
 {'IMEI': '430',
  'Probability': 0.12,
  'RAG': 'G',
  'Timestamp': '2020-07-02 13-29-24'},
 {'IMEI': '658',
  'Probability': 0.12,
  'RAG': 'G',
  'Timestamp': '2020-07-02 13-29-24'},
 {'IMEI': '157',
  'Probability': 0.12,
  'RAG': 'G',
  'Timestamp': '2020-07-02 13-29-24'},
 {'IMEI': '521',
  'Probability': 0.12,
  'RAG': 'G',
  'Timestamp': '2020-07-02 13-29-24'}]
