使用python将非结构化字典列表转换为结构化字典列表

Question

我有以下内容作为输出。

    ['{end_date=2021-09-16 06:00:00, number=CHG1757, requested_by=Tom, cmdb_ci=Checkout, start_date=2021-09-16 03:00:00}',
 '{end_date=2021-09-16 09:00:00, number=CHG17486, requested_by=Bobby, cmdb_ci=Reservation, start_date=2021-09-16 03:00:00}',
 '{end_date=2021-09-16 12:00:00, number=CHG17441, requested_by=Ryan, cmdb_ci=Payment, start_date=2021-09-16 03:00:00}']

需要使用 python 脚本将上述输出转换为结构化的字典列表（见下文）。

 [{'end_date'='2021-09-16 06:00:00', 'number'='CHG1757', 'requested_by'='Tom', 'cmdb_ci'='Checkout', 'start_date'='2021-09-16 03:00:00'}',
 {'end_date'='2021-09-16 09:00:00', 'number'='CHG17486', 'requested_by'='Bobby', 'cmdb_ci'='Reservation', 'start_date'='2021-09-16 03:00:00'}',
 {'end_date'='2021-09-16 12:00:00', 'number'='CHG17441', 'requested_by'='Ryan', 'cmdb_ci'='Payment', 'start_date'='2021-09-16 03:00:00'}']

Praful，你好吗？

您可以尝试使用下面的代码，但仅当所有字符串的长度相同时才有效。

stack = ['{end_date=2021-09-16 06:00:00, number=CHG1757, requested_by=Tom, cmdb_ci=Checkout, start_date=2021-09-16 03:00:00}',
         '{end_date=2021-09-16 09:00:00, number=CHG17486, requested_by=Bobby, cmdb_ci=Reservation, start_date=2021-09-16 03:00:00}',
         '{end_date=2021-09-16 12:00:00, number=CHG17441, requested_by=Ryan, cmdb_ci=Payment, start_date=2021-09-16 03:00:00}']

splited = []
for line in stack:
    splited.append(line.split(','))

dict_to_fill = {}
new_list = []
for item in splited:
    dict_to_fill['end_date'] = item[0][10:]
    dict_to_fill['number'] = item[1][8:]
    dict_to_fill['requested_by'] = item[2][14:]
    dict_to_fill['cmdb_ci'] = item[3][9:]
    dict_to_fill['start_date'] = item[4][12:-1]
    new_list.append(dict_to_fill.copy())

print(new_list)

输出：

[{'end_date': '2021-09-16 06:00:00',
  'number': 'CHG1757',
  'requested_by': 'Tom',
  'cmdb_ci': 'Checkout',
  'start_date': '2021-09-16 03:00:00'},
 {'end_date': '2021-09-16 09:00:00',
  'number': 'CHG17486',
  'requested_by': 'Bobby',
  'cmdb_ci': 'Reservation',
  'start_date': '2021-09-16 03:00:00'},
 {'end_date': '2021-09-16 12:00:00',
  'number': 'CHG17441',
  'requested_by': 'Ryan',
  'cmdb_ci': 'Payment',
  'start_date': '2021-09-16 03:00:00'}]

告诉我是否有效。

再见！

请在下方找到动态代码来解决您的问题：

stack = ['{end_date=2021-09-16 06:00:00, number=CHG1757, requested_by=Tom, cmdb_ci=Checkout, start_date=2021-09-16 03:00:00}',
         '{end_date=2021-09-16 09:00:00, number=CHG17486, requested_by=Bobby, cmdb_ci=Reservation, start_date=2021-09-16 03:00:00}',
         '{end_date=2021-09-16 12:00:00, number=CHG17441, requested_by=Ryan, cmdb_ci=Payment, start_date=2021-09-16 03:00:00}']
         
output = []
for data in stack:
    data = data.replace("{","").replace("}","").split(",")
    format_dict = {}
    for record in data:
        key, value = record.split("=")
        format_dict[key.strip()] = value.strip()
    output.append(format_dict)

print(output)
