MaxCompute py文件是有什么字符限制吗？

MaxCompute py文件是有什么字符限制吗？my_year = int(y_w.split('-')[0])写上就报错呢？ 空格删了在加上也不行，加上7、8行就报错，删了就运行成功： from odps.udf import annotate import datetime @annotate("string->string") class y_w_to_m(object): def evaluate(self,y_w): try: jan4 = datetime.date(2022,1,4) week1 = jan4.isocalendar()[1] first_day = jan4 - datetime.timedelta(days=jan4.isoweekday()-1) if 12 > week1: first_day -= datetime.timedelta(weeks=(12-week1)) return datetime.datetime.strftime(first_day,'%Y%m') except: return null 这个是可以跑通的，先不管数对不对哈 from odps.udf import annotate import datetime @annotate("string->string") class y_w_to_m(object): def evaluate(self,y_w): try: year = int(y_w.split('-')[0]) week = int(y_w.split('-')[1]) jan4 = datetime.date(year,1,4) week1 = jan4.isocalendar()[1] first_day = jan4 - datetime.timedelta(days=jan4.isoweekday()-1) if week>week1: first_day-=datetime.timedelta(weeks=(week-week1)) return datetime.datetime.strftime(first_day,'%Y%m') except: return null 这个就跑不通 select y_w_to_m('2023-10');
