python - 将换行符添加到 Python 编写的 json

Question

我创建了一个新的 JSON 文档来将数据上传到 couchdb 实例。该代码有效。问题是 Python 脚本编写的数据被文本编辑器显示在一行中。有没有办法添加换行符？这是代码:

newdict = {}
outputdict = {} 
docs_list = []

for number, item in enumerate(data['docs']):
    # pprint (item)
    # print item['key'][4]
    newdict["key1"] = item['key'][0]
    newdict["yek1"] = item['key'][1]
    newdict["key2"] = item['key'][2]
    newdict["yek2"] = item['key'][3]
    newdict["key3"] = item['key'][4]
    newdict["yek3"] = item['value']['lat']
    newdict["key4"] = item['value']['long']
    docs_list.append(newdict)

outputdict["docs"] = docs_list
outputdict = json.dumps(outputdict)
pprint (outputdict)

with open("filename.json",'w') as f:
    f.write(outputdict)

来自 this answer试试 outputdict = json.dumps(outputdict, indent=4)与您要缩进的空格数。
