合并表记录

n = int(input()) dict1 ={} for i in range(n): index,value = input().split() index=int(index) value=int(value) # 居然还要判断边界 if 0<=index<=11111111 and 1<=value<=100000: if dict1.get(index): dict1[index]=value + dict1[index] else: dict1[index] = value #print(dict1)
居然要排序,排序注意，我开始index存的是str，导致排序1，11，2这种问题，后来改成int才通过
sort_dict = sorted(dict1.keys()) for i in sort_dict: print(i,dict1[i])
