【问题描述】：

我有一个包含 3 个对象的 JSON 文件，如下所示：

["ID": "44585", "TITLE": "A day in *Australia*=/", "MailThread": ["email": " Its a great day, isn't it.", "email": " Yes, indeed.", "email": " Great Day!!!"], "SUMMARY": "", "NAME": "Mike's Journal", "PRIORITY": 3, "FLIGHTTICKETNO": 25565826, "CODENAME": "ausTrip", "DESC": "I am really feeling great*&^% to be here!! I love this place, and find it's places amazin#@$. Thanks!!","ID": "44585", "TITLE": "A day in *Australia*=/", "MailThread": ["email": " Its a great day, isn't it.", "email": " Yes, indeed.", "email": " Great Day!!!"], "SUMMARY": "", "NAME": "Mike's Journal", "PRIORITY": 3, "FLIGHTTICKETNO": 25565826, "CODENAME": "ausTrip", "DESC": "I am really feeling great*&^% to be here!! I love this place, and find it's places amazin#@$. Thanks!!","ID": "44585", "TITLE": "A day in *Australia*=/", "MailThread": ["email": " Its a great day, isn't it.", "email": " Yes, indeed.", "email": " Great Day!!!"], "SUMMARY": "", "NAME": "Mike's Journal", "PRIORITY": 3, "FLIGHTTICKETNO": 25565826, "CODENAME": "ausTrip", "DESC": "I am really feeling great*&^% to be here!! I love this place, and find it's places amazin#@$. Thanks!!"]

我需要从 TITLE 中删除 *=/、&^#@ 等特殊字符，从所有 3 个对象中删除 MailThread 和 DESC 中的多个电子邮件，并将编辑后的内容写入新的 json 文件。

【问题讨论】：

输出是数据框？还是json？您可以添加所需的输出吗？

输出是 json..刚刚编辑了查询..请再看一遍！！

“我需要牛排”不是问题。

这就是我想要做的import pandas as pd df = pd.read_json('JsonData') jsonobj = df['TITLE'] for i in jsonobj: jsonobj[i].replace('[','') print(jsonobj) 它不起作用，也许这不是要牛排而是要帮忙！

您说您需要删除MailThread 中的多封电子邮件。你的意思是全部删除还是选中？明确说明，如果您提供准确的输出会很好。

【参考方案1】：

只处理TITLE，如需其他请自行处理如下：

$ python demo.py
'PRIORITY': 3, 'TITLE': 'A day in Australia', 'FLIGHTTICKETNO': 25565826, 'MailThread': ['email': " Its a great day, isn't it.", 'email': ' Yes, indeed.', 'email': ' Great Day!!!'], 'CODENAME': 'ausTrip', 'SUMMARY': '', 'NAME': "Mike's Journal", 'ID': '44585', 'DESC': "I am really feeling great*&^% to be here!! I love this place, and find it's places amazin#@$. Thanks!!"
'PRIORITY': 3, 'TITLE': 'A day in Australia', 'FLIGHTTICKETNO': 25565826, 'MailThread': ['email': " Its a great day, isn't it.", 'email': ' Yes, indeed.', 'email': ' Great Day!!!'], 'CODENAME': 'ausTrip', 'SUMMARY': '', 'NAME': "Mike's Journal", 'ID': '44585', 'DESC': "I am really feeling great*&^% to be here!! I love this place, and find it's places amazin#@$. Thanks!!"
'PRIORITY': 3, 'TITLE': 'A day in Australia', 'FLIGHTTICKETNO': 25565826, 'MailThread': ['email': " Its a great day, isn't it.", 'email': ' Yes, indeed.', 'email': ' Great Day!!!'], 'CODENAME': 'ausTrip', 'SUMMARY': '', 'NAME': "Mike's Journal", 'ID': '44585', 'DESC': "I am really feeling great*&^% to be here!! I love this place, and find it's places amazin#@$. Thanks!!"

    for ch in "*=/,&^#@":
        title = title.replace(ch, '')
    return title
