Python

好的，以下是Python的实现代码：

import jieba

# 获取用户输入的诗歌
text = input("请输入一首诗的文本：")

# (1) 分词并统计中文词语数
words = list(jieba.cut(text, cut_all=False))
chinese_words = [word for word in words if '\u4e00' <= word <= '\u9fff']
print("/".join(words))
print("中文词语数是：", len(chinese_words))

# (2) 按照逗号和句号将文本分隔成单句并输出
sentences = text.split('。')
for index, sentence in enumerate(sentences):
    if ',' in sentence:
        sub_sentences = sentence.split(',')
        for sub_index, sub_sentence in enumerate(sub_sentences):
            if sub_index == 0:
                sub_sentence += '，'
            if sub_index == len(sub_sentences) - 1:
                sub_sentence += '。'
            print(sub_sentence.center(20))
    else:
        if sentence:
            sentence += '。'
            print(sentence.center(20))
    if index < len(sentences) - 1:
        print()

运行示例：

请输入一首诗的文本：月亮河宽宽的河,一天我从你身旁过,
月亮/河/宽宽的/河/,/一天/我/从/你/身旁/过/,
中文词语数是： 10

     月亮河宽宽的河，
 一天我从你身旁过。
