如何使用python从Google Spreadsheet获取工作表ID？

我想为Google Spreadsheet Workbook中每个工作表确定一种在URL中获取工作表ID的方法。例如，此工作簿的“ sheet2”的工作表ID为“ 1244369280”，因为其网址为https://docs.google.com/spreadsheets/d/1yd8qTYjRns4_OT8PbsZzH0zajvzguKSKS79dq6j--hnTs/edit#gid=1244369280

我发现的一种方法是提取Google Spreadsheet的XML，因为根据此问题，获取工作表ID的唯一方法是流式化工作表的XML，但是示例在Javascript中，我需要用Python做到这一点

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())

从Google Spreadsheet获取XML的最好方法似乎是使用Gdata，因此我下载了GData并尝试使用自己的凭据运行Google Spreadsheet示例。

但是，这将返回以下错误：

我还应该提到，我一直在使用Gspread作为与Google Spreadsheets进行交互的方法，但是当我运行以下代码时，我得到了帮助，但是我需要具有工作表ID。

gc = gspread.authorize(credentials)
sh = gc.open_by_url('google_spreadsheet_url')
sh.get_id_fields() 
>> {'spreadsheet_id': '1BgCEn-3Nor7UxOEPwD-qv8qXe7CaveJBrn9_Lcpo4W4','worksheet_id': 'oqitk0d'}
