中国有嘻哈——押韵机器人

押韵机器人简介

近来群里看到有人谈起押韵机器，突然想起好多年前的回忆。

心血来潮写了一个押韵机器人。可以识别韵脚、比较韵脚、词汇列表按韵脚分类。

经测试，目前对多音字支持不好：比如唠嗑，唠叨。这种就识别会出错。欢迎大家继续测试，有问题反馈给我。

拼音识别基于pypinyin库实现，具体用法详见其github。

押韵机器人代码

押韵机器人代码文件命名叫“punchliner.py”，代码如下：

from pypinyin import pinyin, lazy_pinyin, Style

words = ["今天","太躁","艾福杰尼","着迷","太绕","心间","限","盛宴","榴莲","亏欠","二百五","腐乳","火锅底料","MC大笑","别跟我唠","我感冒","好不好","太早","住口","兄弟","胸臆","太辣","太大","太炸","我手抖"]

def is_alphabet(uchar):
    rule1 = (uchar >= u'u0041' and uchar<=u'u005a')
    rule2 = (uchar >= u'u0061' and uchar<=u'u007a')
    if rule1 or rule2:
        return True
    else:
        return False

def get_punchline(word):
    last_character = word[len(word)-1]
    last_character_pinyin = pinyin(last_character)[0][0]
    punchline = []
    for the_char in last_character_pinyin:
        if not is_alphabet(the_char):
            punchline.append(last_character_pinyin.split(the_char)[0])
            punchline.append(the_char)
            punchline.append(last_character_pinyin.split(the_char)[1])
    return punchline

def compare_punchline(word1,word2):
    punchline1 = get_punchline(word1)
    punchline2 = get_punchline(word2)
    prefix1 = punchline1[0]
    prefix2 = punchline2[0]
    #前缀尾字母设定不为空
    prefix1_last_char = 'x'
    prefix2_last_char = 'x'
    if prefix1 != '':
        prefix1_last_char = prefix1[len(prefix1)-1]
    if prefix2 != '':
        prefix2_last_char = prefix2[len(prefix2)-1]
    #前缀先决条件，都是i或都不是i才算押韵
    pre_rule1 = (prefix1_last_char == 'i')
    pre_rule2 = (prefix2_last_char == 'i')
    all_i = (pre_rule1 and pre_rule2)
    all_not_i = 'i' not in [prefix1_last_char,prefix2_last_char]
    if all_i or all_not_i:
        rule1 = punchline1[1] == punchline2[1]
        rule2 = punchline1[2] == punchline2[2]
        if rule1 and rule2:
            return True
        else:
            return False
    else:
        return False

def classify_punchline(words_list):
    target = words_list[0]
    yayun_words = filter(lambda word:compare_punchline(target,word)==True,words)
    yayun_words_list = list(set(yayun_words))
    left_words_list = list(set(words_list)-set(yayun_words_list))
    print(yayun_words_list)
    rule1 = left_words_list != words_list
    rule2 = len(left_words_list) > 0
    if rule1 and rule2:
        classify_punchline(left_words_list)
    
if __name__ == '__main__':
    #print(get_punchline("变"))
    #print(get_punchline("案"))
    #print(get_punchline("绕"))
    #print(compare_punchline("安","翻"))
    #print(compare_punchline("变","案"))
    #print(compare_punchline("房","狼"))
    #print(get_punchline("唠"))
    classify_punchline(words)

其中：

1. 函数fuck_yayun可以对词藻列表中的词汇进行判断，把押韵的词汇进行自动归类；

2. 函数get_punchline可以获取词汇韵脚；

3. 函数compare_punchline可以比较韵脚。

希望有朝一日可以像发明AlphaGo一样发明AlphaRapper，让他去参加中国有嘻哈。

运行结果：
