Python-Json编写，不想按我的意愿打印

Question

我试图从我的脚本中进行写操作以使其成为Json文件。

但是，当我用脚本写出来时，它的输出为

{
    "profile_1": {
        "email": "HelloWorld",
        "pswrd": "WorldHello123"
    }
} {
    "profile_2": {
        "email": "HelloWorld",
        "pswrd": "WorldHello123"
    }
} {
    "profile_3": {
        "email": "HelloWorld",
        "pswrd": "WorldHello123"
    }
}

我真正希望的是：

"profile_0": {
            "email": "HelloWorld",
            "pswrd": "WorldHello123"

        },
        "profile_1": {
            "email": "HelloWorld",
            "pswrd": "WorldHello123""
        },
        "profile_2": {
            "email": "HelloWorld",
            "pswrd": "WorldHello123"
        },
        "profile_3": {
            "email": "HelloWorld",
            "pswrd": "WorldHello123"
        },

而且，根据我们的比较，{}太多了，而且也缺少了，我不太明白为什么它行不通。 这是我的脚本的工作方式：

import json

    with open("test.txt") as accounts:
        for splitlines in accounts:
            temp = accounts.read().splitlines()
            username, password = zip(*(s.split(":") for s in temp))
            linelength = len(username)

            with open("profiles.json", "a") as profile:
                lineInt = 0
                while (lineInt < linelength):
                    lineInt += 1
                    jsonData = {
                            "profile_" + str(lineInt): {
                            "email": username[lineInt],
                            "pswrd": password[lineInt]
                            }
                    }
                    json.dump(jsonData, profile)

我坐了太久没看到问题了：'（

您正在逐一输出JSON对象 。 如果要输出JSON数组 ，则应将对象放在列表中，并进行打印，例如：

lineInt = 0
items = []
while (lineInt < linelength):
    jsonData = {
        "profile_" + str(lineInt): {
            "email": username[lineInt],
            "pswrd": password[lineInt]
        }
    }
    lineInt += 1
    items.append(jsonData)
json.dump(items, profile)
