Python 从响应 JSON 中读取特定数据

Question

我是 Python 和 JSON 新手。我正在调用一个 API，并且作为响应正文，我得到以下内容:

{'product': 'Cycle', 'available': 20, 'blocked': 0, 'orderBooked': 0, 'transfer': 0, 'restock': 0, 'unavailable': 0, 'total': 0, 'lCode': '2000112', 'locationId': '745', 'locationCode': '425', 'stockType': 'IN STOCK', 'adminStock': {'rp': 0, 'management': 0, 'rc': 0, 'total': 0, 'default': 0}, 'isBlocked': False, 'plannedDate': None, 'plannedUpdate': True, 'bookedQuantity': 0}
{'product': 'Cooker', 'available': 958, 'blocked': 10, 'orderBooked': 10, 'transfer': 30, 'restock': 0, 'unavailable': 0, 'total': 0, 'lCode': '589620', 'locationId': '420', 'locationCode': '695', 'stockType': 'PRE ORDER', 'adminStock': {'rp': 0, 'management': 0, 'rc': 0, 'total': 0, 'default': 0}, 'isBlocked': False, 'plannedDate': None, 'plannedUpdate': True, 'bookedQuantity': 0}
{'product': 'Cycle', 'available': 96220, 'blocked': 0, 'orderBooked': 0, 'transfer': 0, 'restock': 0, 'unavailable': 0, 'total': 0, 'lCode': '2000112', 'locationId': '745', 'locationCode': '425', 'stockType': 'CONFIRMED', 'adminStock': {'rp': 0, 'management': 0, 'rc': 0, 'total': 0, 'default': 0}, 'isBlocked': False, 'plannedDate': None, 'plannedUpdate': True, 'bookedQuantity': 0}
{'product': 'Lapms', 'available': 89958, 'blocked': 1890, 'orderBooked': 1045, 'transfer': 230, 'restock': 0, 'unavailable': 0, 'total': 0, 'lCode': '78963', 'locationId': '896', 'locationCode': '463', 'stockType': 'TRANSIT', 'adminStock': {'rp': 0, 'management': 0, 'rc': 0, 'total': 0, 'default': 0}, 'isBlocked': False, 'plannedDate': None, 'plannedUpdate': True, 'bookedQuantity': 0}

我上面提到的数据将根据 API 请求而变化。所以无论 react 如何。根据产品，我需要打印多行数据。我的请求是读取此 Json 并获取以下数据:

Name:<'product'>, Code:<'lCode'>, Location:<'locationCode'>, Stock Type:<'stockType'>, Availability:<'available'>

所以对于上面的 Json，输出应该是这样的:

Name:Cycle, Code:2000112, Location:425, Stock Type:PRE ORDER, Availability:20
Name:Cooker, Code:589620, Location:695, Stock Type:<'stockType'>, Availability:958
Name:Cycle, Code:2000112, Location:425, Stock Type:CONFIRMED, Availability:96220
Name:Lapms, Code:78963, Location:463, Stock Type:TRANSIT, Availability:89958

所以基于时代，

product is occuring, the data output will be having that much lines

我对用Python解析Json没有任何想法。请帮助理解我如何获取以下格式的数据。我还没有尝试过任何东西，因为我被卡住了

Answer 1

我相信这就是你想要的。正如一些评论所说，实际上这些输出应该被视为字典或列表，其中嵌套有字典和/或列表。了解差异很重要，因为第一个应该通过其key 来寻址，而后者应通过其index 来寻址。您可以找到一些有关如何读取 jsons/dictionary here 的额外信息

import pandas as pd
json_1 = {'product': 'Cycle', 'available': 20, 'blocked': 0, 'orderBooked': 0, 'transfer': 0, 'restock': 0, 'unavailable': 0, 'total': 0, 'lCode': '2000112', 'locationId': '745', 'locationCode': '425', 'stockType': 'IN STOCK', 'adminStock': {'rp': 0, 'management': 0, 'rc': 0, 'total': 0, 'default': 0}, 'isBlocked': False, 'plannedDate': None, 'plannedUpdate': True, 'bookedQuantity': 0}
json_2 = {'product': 'Cooker', 'available': 958, 'blocked': 10, 'orderBooked': 10, 'transfer': 30, 'restock': 0, 'unavailable': 0, 'total': 0, 'lCode': '589620', 'locationId': '420', 'locationCode': '695', 'stockType': 'PRE ORDER', 'adminStock': {'rp': 0, 'management': 0, 'rc': 0, 'total': 0, 'default': 0}, 'isBlocked': False, 'plannedDate': None, 'plannedUpdate': True, 'bookedQuantity': 0}
json_3 = {'product': 'Cycle', 'available': 96220, 'blocked': 0, 'orderBooked': 0, 'transfer': 0, 'restock': 0, 'unavailable': 0, 'total': 0, 'lCode': '2000112', 'locationId': '745', 'locationCode': '425', 'stockType': 'CONFIRMED', 'adminStock': {'rp': 0, 'management': 0, 'rc': 0, 'total': 0, 'default': 0}, 'isBlocked': False, 'plannedDate': None, 'plannedUpdate': True, 'bookedQuantity': 0}
json_4 = {'product': 'Lapms', 'available': 89958, 'blocked': 1890, 'orderBooked': 1045, 'transfer': 230, 'restock': 0, 'unavailable': 0, 'total': 0, 'lCode': '78963', 'locationId': '896', 'locationCode': '463', 'stockType': 'TRANSIT', 'adminStock': {'rp': 0, 'management': 0, 'rc': 0, 'total': 0, 'default': 0}, 'isBlocked': False, 'plannedDate': None, 'plannedUpdate': True, 'bookedQuantity': 0}
support_list = []
support_list.append([json_1,json_2,json_3,json_4])
support_dict = {'Name':[],'Code':[],'Location':[],'Stock type':[],'Availability':[]}

for i in range(len(support_list[0])):
    support_dict['Name'].append(support_list[0][i]['product'])
    support_dict['Code'].append(support_list[0][i]['lCode'])
    support_dict['Location'].append(support_list[0][i]['locationCode'])
    support_dict['Stock type'].append(support_list[0][i]['stockType'])
    support_dict['Availability'].append(support_list[0][i]['available'])
df = pd.DataFrame(support_dict)
print(df)

输出:

     Name     Code Location Stock type  Availability
0   Cycle  2000112      425   IN STOCK            20
1  Cooker   589620      695  PRE ORDER           958
2   Cycle  2000112      425  CONFIRMED         96220
3   Lapms    78963      463    TRANSIT         89958

编辑:OPs 说它只是包含多个 json 的列表。

它应用相同的逻辑:

import pandas as pd
json_output= [{'product': 'Cycle', 'available': 20, 'blocked': 0, 'orderBooked': 0, 'transfer': 0, 'restock': 0, 'unavailable': 0, 'total': 0, 'lCode': '2000112', 'locationId': '745', 'locationCode': '425', 'stockType': 'IN STOCK', 'adminStock': {'rp': 0, 'management': 0, 'rc': 0, 'total': 0, 'default': 0}, 'isBlocked': False, 'plannedDate': None, 'plannedUpdate': True, 'bookedQuantity': 0},{'product': 'Cooker', 'available': 958, 'blocked': 10, 'orderBooked': 10, 'transfer': 30, 'restock': 0, 'unavailable': 0, 'total': 0, 'lCode': '589620', 'locationId': '420', 'locationCode': '695', 'stockType': 'PRE ORDER', 'adminStock': {'rp': 0, 'management': 0, 'rc': 0, 'total': 0, 'default': 0}, 'isBlocked': False, 'plannedDate': None, 'plannedUpdate': True, 'bookedQuantity': 0},{'product': 'Cycle', 'available': 96220, 'blocked': 0, 'orderBooked': 0, 'transfer': 0, 'restock': 0, 'unavailable': 0, 'total': 0, 'lCode': '2000112', 'locationId': '745', 'locationCode': '425', 'stockType': 'CONFIRMED', 'adminStock': {'rp': 0, 'management': 0, 'rc': 0, 'total': 0, 'default': 0}, 'isBlocked': False, 'plannedDate': None, 'plannedUpdate': True, 'bookedQuantity': 0},{'product': 'Lapms', 'available': 89958, 'blocked': 1890, 'orderBooked': 1045, 'transfer': 230, 'restock': 0, 'unavailable': 0, 'total': 0, 'lCode': '78963', 'locationId': '896', 'locationCode': '463', 'stockType': 'TRANSIT', 'adminStock': {'rp': 0, 'management': 0, 'rc': 0, 'total': 0, 'default': 0}, 'isBlocked': False, 'plannedDate': None, 'plannedUpdate': True, 'bookedQuantity': 0}]
support_dict = {'Name':[],'Code':[],'Location':[],'Stock type':[],'Availability':[]}

for i in range(len(json_output)):
    support_dict['Name'].append(json_output[i]['product'])
    support_dict['Code'].append(json_output[i]['lCode'])
    support_dict['Location'].append(json_output[i]['locationCode'])
    support_dict['Stock type'].append(json_output[i]['stockType'])
    support_dict['Availability'].append(json_output[i]['available'])
df = pd.DataFrame(support_dict)
print(df)

输出:

     Name     Code Location Stock type  Availability
0   Cycle  2000112      425   IN STOCK            20
1  Cooker   589620      695  PRE ORDER           958
2   Cycle  2000112      425  CONFIRMED         96220
3   Lapms    78963      463    TRANSIT         89958

编辑2:如果您希望输出为行:

json_output= [{'product': 'Cycle', 'available': 20, 'blocked': 0, 'orderBooked': 0, 'transfer': 0, 'restock': 0, 'unavailable': 0, 'total': 0, 'lCode': '2000112', 'locationId': '745', 'locationCode': '425', 'stockType': 'IN STOCK', 'adminStock': {'rp': 0, 'management': 0, 'rc': 0, 'total': 0, 'default': 0}, 'isBlocked': False, 'plannedDate': None, 'plannedUpdate': True, 'bookedQuantity': 0},{'product': 'Cooker', 'available': 958, 'blocked': 10, 'orderBooked': 10, 'transfer': 30, 'restock': 0, 'unavailable': 0, 'total': 0, 'lCode': '589620', 'locationId': '420', 'locationCode': '695', 'stockType': 'PRE ORDER', 'adminStock': {'rp': 0, 'management': 0, 'rc': 0, 'total': 0, 'default': 0}, 'isBlocked': False, 'plannedDate': None, 'plannedUpdate': True, 'bookedQuantity': 0},{'product': 'Cycle', 'available': 96220, 'blocked': 0, 'orderBooked': 0, 'transfer': 0, 'restock': 0, 'unavailable': 0, 'total': 0, 'lCode': '2000112', 'locationId': '745', 'locationCode': '425', 'stockType': 'CONFIRMED', 'adminStock': {'rp': 0, 'management': 0, 'rc': 0, 'total': 0, 'default': 0}, 'isBlocked': False, 'plannedDate': None, 'plannedUpdate': True, 'bookedQuantity': 0},{'product': 'Lapms', 'available': 89958, 'blocked': 1890, 'orderBooked': 1045, 'transfer': 230, 'restock': 0, 'unavailable': 0, 'total': 0, 'lCode': '78963', 'locationId': '896', 'locationCode': '463', 'stockType': 'TRANSIT', 'adminStock': {'rp': 0, 'management': 0, 'rc': 0, 'total': 0, 'default': 0}, 'isBlocked': False, 'plannedDate': None, 'plannedUpdate': True, 'bookedQuantity': 0}]

for i in range(len(json_output)):
    print('Name: ' + str(json_output[i]['product']) + ', Code: ' + str(json_output[i]['lCode']) + ', Location: ' + str(json_output[i]['locationCode']) + ', Stock type: ' + str(json_output[i]['stockType']) + ', Availability: ' + str(json_output[i]['available']))

输出:
