大约六个月前，我编写了一些代码来访问 Smartsheet API，当我回来时，这些代码不再起作用。例如，
import smartsheet
api_key = "ABCD1234"
smartsheet_client = smartsheet.Smartsheet(api_key)
smartsheet_client.errors_as_exceptions(True)
print("Hello World\n")
sheets = smartsheet_client.Sheets.list_sheets(include_all=True).data
print(sheets)
现在将输出：
Hello World
