题解 | #合并表记录#python 字典可读取多段输入方法

貌似大家都假定是一段数据，我这个可以读入多段数据。 即可处理如下输入：
3
3 1
2 2
1 3
4
0 1
0 2
3 1
2 1

data = []
while True:
    try:
        sub_data = str(input())
        data.append(sub_data)
    except:
        break
dic = {}
i = 0
while i < len(data):
    index_len = int(data[i])
    start = i+1
    end = start + index_len
    for j in range(start,end):
        key,value = data[j].split(" ")
        key,value =int(key),int(value)
        if key not in dic:
            dic[key] = value
        else:
            dic[key] = dic[key] + value
    i = end

sortDic = dict(sorted(dic.items(), key = lambda x:x[0], reverse = False))
for k,v in sortDic.items():
    print(k,v)
