【问题描述】：
所以我是 python 新手（这是关于堆栈溢出的第一篇文章）。我正在尝试使用 python 向谷歌驱动器帐户上传和下载文件（并最终在定制的工作 tiki wiki 上引用来自该驱动器的文件）。下面的代码来自谷歌的 python api 资源。它将成功列出我驱动器上的文件（应该如此）。但是，当我尝试上传文件时（请参阅底部的第 10 行），我收到以下错误：
An error occured: <HttpError 403 "Insufficient Permission">
我已经四处寻找了几个小时，但我不知道如何解决这个问题。我想我需要请求某种令牌。不太确定。再说一次，我是新手。任何帮助将不胜感激！
