任务一

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。

Eg:

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': 3,'an': 1,'example': 1,'word': 1, 
'count': 2,'fun': 1,'Is': 1,'it': 2,'to': 1,'words': 1,'Yes': 1,'fun': 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。

任务一解答

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.
"""

import re
from collections import Counter

def wordcount(text: str):
    # 去除标点符号
    text = re.sub(f"[!.,?]", "", text)

    # 转换为小写并分割单词
    words = text.lower().split()

    # 统计单词
    return dict(Counter(words))

print(wordcount(text))

任务二

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)。

任务二解答

本地vscode用ssh连接远程开发机。

打开 /root/ 目录，创建 l0-python.py 文件，写入任务一解答的内容；此时 VS Code 会提示下载 Python 扩展，下载扩展即可。

下载完扩展后，设置断点，开始调试。

选择 Python Debugger: Debug using launch.json 会在 ~/.vscode/ 目录下生成 launch.json 配置文件，内容如下：

{
    // Use IntelliSense to learn about possible attributes.
    // Hover to view descriptions of existing attributes.
    // For more information, visit: https://go.microsoft.com/fwlink/?linkid=830387
    "version": "0.2.0",
    "configurations": [
        {
            "name": "Python Debugger: Current File",
            "type": "debugpy",
            "request": "launch",
            "program": "${file}",
            "console": "integratedTerminal"
        }
    ]
}

进入 Python 调试后，用上方的按钮进行 Continue，Step Over 等操作；左侧出现 VARIABLES 视图，显示局部和全局变量。

调试结束，输出结果。
