Tableau REST API允许您通过Python刷新数据提取。
下面是一个example脚本，它应该让你开始：

import tableauserverclient as TSC

tableau_auth = TSC.TableauAuth(user, password)
server = TSC.Server('Address')
server.version = '2.3'
resource_id= 6109
with server.auth.sign_in(tableau_auth):
print('connection made')
print(server.version)
#resource = server.workbooks.get_by_id(resource_id)
server.workbooks.refresh(workbook_id='6109')

server.auth.sign_out()
print('connection closed')
