• Python实现wordcount
• Vscode连接InternStudio debug笔记

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 and
super cute, and its face has a friendly look. It's
a bit small for what I paid though. I think there
might be other options that are bigger for the
same price. It arrived a day earlier than expected,
so I got to play with it myself before I gave it
to her.
"""

def wordcount(text):
    pass

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 = """

who loves it and takes it everywhere. It's soft and
super cute, and its face has a friendly look. It's
a bit small for what I paid though. I think there
might be other options that are bigger for the
same price. It arrived a day earlier than expected,
so I got to play with it myself before I gave it
to 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。
