这段代码是一个 Python 的字数统计程序,它的作用是读取一个字符串,将其中的逗号替换为空格,并统计每个单词在字符串中出现的次数。
具体来说,这段代码的流程如下:
1. 首先定义一个字符串 txt,其中包含有一段文本。
2. 然后调用 txt.replace() 方法,将字符串中的逗号替换为空格,得到一个新的字符串。
3. 接着调用 txt.split() 方法,将字符串按照空格进行分割,得到一个单词列表 words。
4. 定义一个字典 counts,用于存储每个单词在字符串中出现的次数。
5. 对于列表中的每个单词,使用字典的 get() 方法获取其在字典中的出现次数,如果该单词在字典中不存在,则默认其出现次数为 0。
6. 将该单词的出现次数加 1,并将其更新到字典中。
7. 最后,使用字符串的 format() 方法将单词和其出现次数格式化输出。
需要注意的是,由于字符串中的标点符号和大小写会影响单词的统计,因此在进行单词统计时需要对字符串进行预处理以去除这些影响。

The art form features a unique combination of singing, dancing, music, and acrobatics, all performed by highly skilled actors in exquisite costumes and makeup.

It is a form of expression that can convey a wide spectrum of emotions, from joy and humour to sadness and tragedy. The performers use a range of skills, such as voice modulation, facial expressions, and body language, to convey their character's emotions and intentions. The audience is also an important part of the opera, where they can interact with the performers and express their appreciation with cheers and applause. Today, traditional Chinese opera remains a vibrant and beloved form of entertainment that is enjoyed by people all over the world.
