我正在摆弄输出一个json文件,其中包含目录中文件的一些属性.我的问题是,当附加到文件时,每个对象之间没有分隔符.我可以在每个'f'之后添加一个逗号并删除最后一个,但这对我来说似乎是一个草率的工作.

import os
import os.path
import json

#Create and open file_data.txt and append 
with open('file_data.txt', 'a') as outfile:

    files = os.listdir(os.curdir)


    for f in files:

        extension = os.path.splitext(f)[1][1:]
        base = os.path.splitext(f)[0]
        name = f

        data = {
            "file_name" : name,
            "extension" : extension,
            "base_name" : base
                }

        json.dump(data, outfile)

这输出:

{"file_name": "contributors.txt", "base_name": "contributors", "extension": "txt"}{"file_name": "read_files.py", "base_name": "read_files", "extension": "py"}{"file_name": "file_data.txt", "base_name": "file_data", "extension": "txt"}{"file_name": ".git", "base_name": ".git", "extension": ""}

我想要的是实际的JSON:

{"file_name": "contributors.txt", "base_name": "contributors", "extension": "txt"},{"file_name": "read_files.py", "base_name": …

我有一个 Django 应用程序，我试图在带有 Gunicorn 的 Ubunutu VPS 上设置，但在运行时遇到错误gunicorn project:application -b myip:8000。这是结果的输出：
