【问题描述】：
我正在尝试制作一个可以读取和写入谷歌电子表格的 python 脚本。我基本上复制了https://developers.google.com/sheets/quickstart/python 的python 快速启动脚本，并使用https://developers.google.com/resources/api-libraries/documentation/sheets/v4/python/latest/ 的参考对其进行了修改。
使用快速启动脚本中显示的“get”方法一切正常。我可以毫无错误地阅读工作表。要使用“更新”而不是“获取”（写入工作表而不是阅读），我删除了范围 URL 的 .readonly 部分。我还用update() 替换了get() 方法，并将body 作为参数包含在update() 方法中，其中包含用json.dumps 编码的值的json 对象。这都是根据上面的第二个参考。
对于“无效数据”，我每次都会收到 HttpError 400。
代码：

【问题讨论】：
-
您能否提供您在问题中尝试的代码而不是链接？
-
您使用的 .json 文件可能不是正确的，请提供控制台错误跟踪，它应该为我们指明正确的方向。
