我想确定一种方法来获取 Google 电子表格工作簿中每个工作表的 URL 中的工作表 ID。例如，此工作簿的 'sheet2' 的工作表 ID是 '1244369280' ，因为它的 url 是https://docs.google.com/spreadsheets/d/1yd8qTYjRns4_OT8PbsZzH0zajvzguKS79dq6j--hnTs/edit#gid=1244369280
我发现的一种方法是提取 Google 电子表格的 XML，因为根据这个问题，获取工作表 ID 的唯一方法是流式传输工作表的 XML，但该示例是用 Javascript 编写的，我需要在 Python 中执行此操作
这是我想在 Python 中执行的 Javascript 代码：
Dim worksheetFeed As WorksheetFeed
Dim query As WorksheetQuery
Dim worksheet As WorksheetEntry
Dim output As New MemoryStream
Dim xml As String
Dim gid As String = String.Empty
Try
_service = New Spreadsheets.SpreadsheetsService("ServiceName")
_service.setUserCredentials(UserId, Password)
query = New WorksheetQuery(feedUrl)
worksheetFeed = _service.Query(query)
worksheet = worksheetFeed.Entries(0)
' Save worksheet feed to memory stream so we can
' get the xml returned from the feed url and look for
' the gid. Gid allows us to download the specific worksheet tab
Using output
worksheet.SaveToXml(output)
End Using
xml = Encoding.ASCII.GetString(output.ToArray())
似乎从 Google 电子表格获取 XML 的最佳方式是使用 Gdata，因此我下载了 GData 并使用我的凭据尝试了 Google 电子表格示例。

我还应该提到，我一直在使用 Gspread 作为与 Google 电子表格交互的方法，但是当我运行下面的代码时，我得到了 gid，但我需要有工作表 id。
gc = gspread.authorize(credentials)
sh = gc.open_by_url('google_spreadsheet_url')
sh.get_id_fields()
