python去掉ufeff,xa0,u3000。不知道为什么，utf-8会遇到bom的问题，所以Ori会给\u2022defu8togbk(self,infn,outfn):withopen(infn,'r',encoding='utf-8')作为f:reader=csv.reader(f)results=list(reader)results[0][0]=results[0][0].replace('\ufeff','').replace('\xa0','').replace('\u3000','').replace('\u2022','')以open(outfn,'w',encoding='gbk',newline='')asf:writer=csv.writer(f)结果结果：writer.writerow(result)
