我是python的新手，正在尝试以下代码

class Arm(object):
def __init__(self, SNo, ActivityDate, RequesterTeam, RequesterSignumId, RequesterEmailId,Circle,Customer,Technology,WOType,ProblemTitle,ActivityTypeorEqType,SiteID,BSCFACID,EngineerName,EngineerSignum,DetailDescriptionOfActivityToBePerformed,TimelineforActivityCompletion,WOIDbyWFM ):
