实践流程
实现wordcount
请实现一个wordcount函数，统计英文字符串中每个单词出现的次数。返回一个字典，key为单词，value为对应单词出现的次数。
Input:
"""Hello world!This is an example.Word count is fun.Is it fun to count words?Yes, it is fun!"""Output:
{'hello': 1, 'world': 1, 'this': 1, 'is': 4, 'an': 1, 'example': 1, 'word': 1, 'count': 2,'fun': 3, 'it': 2, 'to': 1, 'words': 1, 'yes': 1}TIPS：记得先去掉标点符号,然后把每个单词转换成小写。不需要考虑特别多的标点符号，只需要考虑实例输入中存在的就可以。
text = """Got this panda plush toy for my daughter's birthday,who loves it and takes it everywhere. It's soft andsuper cute, and its face has a friendly look. It'sa bit small for what I paid though. I think theremight be other options that are bigger for thesame price. It arrived a day earlier than expected,so I got to play with it myself before I gave itto her."""
def wordcount(text): pass直接交给kimi
实际代码
text = """Hello world!This is an example.Word count is fun.Is it fun to count words?Yes, it is fun!"""
text1 = """Got this panda plush toy for my daughter's birthday,who loves it and takes it everywhere. It's soft andsuper cute, and its face has a friendly look. It'sa bit small for what I paid though. I think theremight be other options that are bigger for thesame price. It arrived a day earlier than expected,so I got to play with it myself before I gave itto her."""
import re
def wordcount(text): # 将文本转换为小写 text = text.lower() # 使用正则表达式移除标点符号 text = re.sub(r'[^\w\s]', '', text) # 分割文本为单词列表 words = text.split() # 创建一个字典来存储单词计数 word_count = {} # 遍历单词列表，计数 for word in words: if word in word_count: word_count[word] += 1 else: word_count[word] = 1 return word_count
print(wordcount(text))print(wordcount(text1))测试结果
连接InternStudio debug笔记
请使用本地vscode连接远程开发机，将上面你写的wordcount函数在开发机上进行debug，体验debug的全流程，并完成一份debug笔记(需要截图)。
在32行打点，表示第一次达到这个点的时候，应该是有一个单词已经出现过一次，才会进入这一行，查看text文本，这里进入的word是is，is正好出现第二次
选择单步运行，发现word_count里面的is对应的数值已经是2了，增加了1
取消32行断点，设置35行断点，直接运行到该断点，左侧统计出了该text文本段所有词汇的出现次数。
总结
温故知新，debug很好用，不要再总是一次次print了。ai编程也是个好东西，提高生产力。
