程序运行无法结束
import math; def dictSlice(dic, n, m): # print dic; lst = dic.keys(); # print lst; lst = sorted(lst, lambda x, y: cmp(x, y)); # print 4; lst = lst[(n - 1 if(n <= m) else m - 1): (n if(n >= m) else m)]; newDic = {}; for i in lst: newDic[i] = dic[i]; # print newDic; return newDic; newLst = []; reLst = []; while True: try: # print math.min(9, 9); n = raw_input(); # print n; inLst = map(int, n.split(' ')); # print inLst; lst1 = map(int, raw_input().split(' ')); lst = zip(range(1, inLst[0] + 1), lst1); # print lst; dic = dict(lst); # print dic; while(inLst[1] >= 1): inLst[1] = inLst[1] - 1; # print 1; newLst = raw_input().split(' '); # print int(newLst[1]); if newLst[0] == 'Q': # print 2; dic1 = dictSlice(dic, int(newLst[1]), int(newLst[-1])); reLst.append(dic1.get(max(dic1, key = dic1.get))); elif newLst[0] == 'U': dic[int(newLst[1])] = int(newLst[2]); for num in reLst: print num; except: break;
我的代码在最后一次输入之后打印完不能结束是为什么,是哪里出了错误?
谢谢
