while True:
    try:
        words = list(map(str,input()))
        dic_words={}
        new_words = ''
        for word in words:
            if word not in dic_words:
                dic_words[word]=1
            else:
                dic_words[word]+=1
        min_value = min(dic_words.values())
        for word in words:
            if dic_words[word]>min_value:
                new_words+=word
        print(new_words)
    except:
        break

读懂题意很重要，读错了两次。

1. dictionary 的用法 min(dic_words.values())可以得到value最小值
2. 字符串用法
