python - 在每个文件合并后添加换行符

Question

我有很多 JSON 文件，如下所示：

例如

1.json

{"name": "one", "description": "testDescription...", "comment": ""}

test.json

{"name": "test", "description": "testDescription...", "comment": ""}

two.json

{"name": "two", "description": "testDescription...", "comment": ""}

...

我想将它们全部合并到一个 JSON 文件中，例如：

merge_json.json

{"name": "one", "description": "testDescription...", "comment": ""},
{"name": "test", "description": "testDescription...", "comment": ""},
{"name": "two", "description": "testDescription...", "comment": ""}

我有以下代码：

import json
import glob

result = []
for f in glob.glob("*.json"):
    with open(f, "r") as infile:
        try:
            result.append(json.load(infile))
        except ValueError as e:
            print(f,e)
result = '\n'.join(result)

with open("merged.json", "w", encoding="utf8") as outfile:
    json.dump(result, outfile)

我可以合并所有文件，但是所有文件都在一行中，添加每个文件后如何添加换行符：

代替：

{"name": "one", "description": "testDescription...", "comment": ""},{"name": "test", "description": "testDescription...", "comment": ""},{"name": "two", "description": "testDescription...", "comment": ""}

让他们喜欢：

merge_json.json

{"name": "one", "description": "testDescription...", "comment": ""},
{"name": "test", "description": "testDescription...", "comment": ""},
{"name": "two", "description": "testDescription...", "comment": ""}

感谢任何帮助。

        except ValueError as e:
            print(f,e)

with open("merged.json", "a", encoding="utf8") as outfile:
    for i in result:
        json.dump(i, outfile)
        outfile.write('\n')
