我正在从firebase下载数据,并将其导出为json。在此之后,我试图将其上传到bigquery,但我需要删除bigquery的新行提要才能接受它。

我正在使用python加载json,读取它,然后编写一个新的json,但无法找到正确的代码。非常感谢。

下面是我的python代码的大纲

import json
with open('nospacetest.json', 'r') as f:
  data_json=json.load(f)

#b= the file after code for no line breaks is added

with open('testnoline.json', 'w') as outfile:
  json.dump=(b, outfile)

你只需要确保 indent=None 当你 dump

with open('testnoline.json', 'w') as outfile:   
    json.dump(data_json, outfile, indent=None)

引用文件:

indent 是一个非负整数,那么JSON数组元素和对象成员将以该缩进级别打印出来。缩进级别为0或负值时,只会插入换行符。 None (默认值)选择最紧凑的表示。

with open('testnoline.json', 'w') as outfile:
    for obj in data_json:
        outfile.write(json.dumps(obj) + "\n")
