根據 python 的條件刪除/過濾 JSON 中的行

Question

我在 JSON 中有一個表，如果“交易類型”中的“處置（非公開市場）”然后刪除/過濾所有列中的條目，我需要根據條件刪除/過濾整行。 下面是我的 JSON 文件的樣子：

{
    "lastDate":{
        "0":"11\/22\/2022",
        "1":"10\/28\/2022",
        "2":"10\/17\/2022",
        "3":"10\/15\/2022",
        "4":"10\/15\/2022",
        "5":"10\/15\/2022",
        "6":"10\/15\/2022",
        "7":"10\/03\/2022",
        "8":"10\/03\/2022",
        "9":"10\/03\/2022",
        "10":"10\/01\/2022",
        "11":"10\/01\/2022",
        "12":"10\/01\/2022",
        "13":"10\/01\/2022",
        "14":"10\/01\/2022",
        "15":"10\/01\/2022",
        "16":"10\/01\/2022",
        "17":"10\/01\/2022",
        "18":"08\/17\/2022",
        "19":"08\/08\/2022",
        "20":"08\/05\/2022",
        "21":"08\/05\/2022",
        "22":"08\/03\/2022",
        "23":"05\/06\/2022",
        "24":"05\/04\/2022"
    },
    "transactionType":{
        "0":"Sell",
        "1":"Automatic Sell",
        "2":"Automatic Sell",
        "3":"Disposition (Non Open Market)",
        "4":"Option Execute",
        "5":"Disposition (Non Open Market)",
        "6":"Option Execute",
        "7":"Automatic Sell",
        "8":"Sell",
        "9":"Automatic Sell",
        "10":"Disposition (Non Open Market)",
        "11":"Option Execute",
        "12":"Disposition (Non Open Market)",
        "13":"Option Execute",
        "14":"Disposition (Non Open Market)",
        "15":"Option Execute",
        "16":"Disposition (Non Open Market)",
        "17":"Option Execute",
        "18":"Automatic Sell",
        "19":"Automatic Sell",
        "20":"Disposition (Non Open Market)",
        "21":"Option Execute",
        "22":"Automatic Sell",
        "23":"Disposition (Non Open Market)",
        "24":"Automatic Sell"
    },
    "sharesTraded":{
        "0":"20,200",
        "1":"176,299",
        "2":"8,053",
        "3":"6,399",
        "4":"13,136",
        "5":"8,559",
        "6":"16,612",
        "7":"167,889",
        "8":"13,250",
        "9":"176,299",
        "10":"177,870",
        "11":"365,600",
        "12":"189,301",
        "13":"365,600",
        "14":"184,461",
        "15":"365,600",
        "16":"189,301",
        "17":"365,600",
        "18":"96,735",
        "19":"15,366",
        "20":"16,530",
        "21":"31,896",
        "22":"25,000",
        "23":"1,276",
        "24":"25,000"
    }
}

我當前的代碼是嘗試刪除/過濾掉值為“處置（非公開市場）”的條目：

import json

data = json.load(open("AAPL22_institutional_table_MRKTVAL.json"))

modified = lambda feature: 'Disposition (Non Open Market)' not in feature['transactionType']
data2 = filter(modified, data)

open("AAPL22_institutional_table_MRKTVAL.json", "w").write(
    json.dumps(data2, indent=4))

首選 output JSON（顯示在所有 3 列上刪除的條目）：

{
    "lastDate":{
        "0":"11\/22\/2022",
        "1":"10\/28\/2022",
        "2":"10\/17\/2022",
        "4":"10\/15\/2022",
        "6":"10\/15\/2022",
        "7":"10\/03\/2022",
        "8":"10\/03\/2022",
        "9":"10\/03\/2022",
        "11":"10\/01\/2022",
        "13":"10\/01\/2022",
        "15":"10\/01\/2022",
        "17":"10\/01\/2022",
        "18":"08\/17\/2022",
        "19":"08\/08\/2022",
        "21":"08\/05\/2022",
        "22":"08\/03\/2022",
        "24":"05\/04\/2022"
    },
    "transactionType":{
        "0":"Sell",
        "1":"Automatic Sell",
        "2":"Automatic Sell",
        "4":"Option Execute",
        "6":"Option Execute",
        "7":"Automatic Sell",
        "8":"Sell",
        "9":"Automatic Sell",
        "11":"Option Execute",
        "13":"Option Execute",
        "15":"Option Execute",
        "17":"Option Execute",
        "18":"Automatic Sell",
        "19":"Automatic Sell",
        "21":"Option Execute",
        "22":"Automatic Sell",
        "24":"Automatic Sell" 
    },
    "sharesTraded":{
        "0":"20,200",
        "1":"176,299",
        "2":"8,053",
        "4":"13,136",
        "6":"16,612",
        "7":"167,889",
        "8":"13,250",
        "9":"176,299",
        "11":"365,600",
        "13":"365,600",
        "15":"365,600",
        "17":"365,600",
        "18":"96,735",
        "19":"15,366",
        "21":"31,896",
        "22":"25,000",
        "24":"25,000"
    }
}

Answer 1

我能夠通過將具有字符串值的鍵附加到列表然后簡單地刪除它來根據值刪除

import json

data = json.load(open("AAPL22_institutional_table_MRKTVAL.json"))

delete_keys = []

for value in data['transactionType']:
    if data['transactionType'][value] == 'Disposition (Non Open Market)':
        delete_keys.append(value)

print(delete_keys)

for key in delete_keys:
    del data['transactionType'][key]
    del data['lastDate'][key]
    del data['sharesTraded'][key]

print(data)

open("AAPL22_institutional_table_MRKTVAL.json", "w").write(
    json.dumps(data, indent=4))

Answer 2

data = { "lastDate":{ "0":"11\/22\/2022", "1":"10\/28\/2022", "2":"10\/17\/2022", "3":"10\/15\/2022", "4":"10\/15\/2022", "5":"10\/15\/2022", "6":"10\/15\/2022", "7":"10\/03\/2022", "8":"10\/03\/2022", }, "transactionType":{ "0":"Sell", "1":"Automatic Sell", "2":"Automatic Sell", "3":"Disposition (Non Open Market)", "4":"Option Execute", "5":"Disposition (Non Open Market)", "6":"Option Execute", "7":"Automatic Sell", "8":"Sell", }, "sharesTraded":{ "0":"20,200", "1":"176,299", "2":"8,053", "3":"6,399", "4":"13,136", "5":"8,559", "6":"16,612", "7":"167,889", "8":"13,250", } } for k,v in data["transactionType"].copy().items(): if v == "Disposition (Non Open Market)": for key in data: # Remove the key from all other nested dictionaries del data[key][k] print(data)
