如何从字符串中删除重复的单词，并只显示一次其单词计数

def remove_duplicate_words(string):
    word_list = string.split()  # 拆分字符串为单词列表
    word_count = {}  # 存储单词计数的字典

    # 更新字典中的单词计数
    for word in word_list:
        if word in word_count:
            word_count[word] += 1
        else:
            word_count[word] = 1

    result = ""  # 存储结果的字符串

    # 构建结果字符串
    for word, count in word_count.items():
        result += f"{word}({count}) "

    return result.strip()  # 返回结果字符串，去除末尾的空格

# 示例用法
string = "how much wood would a woodchuck chuck if a woodchuck could chuck wood"
result = remove_duplicate_words(string)
print(result)

how(1) much(1) wood(2) would(1) a(2) woodchuck(2) chuck(2) if(1) could(1)
