InternStudio关卡（Python）

任务一:wordcount函数

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。
在开发机中创建python_task1.py文件，输入以下内容，并且运行python python_task1.py

# 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。
import string


def wordcount(s):
    # 去掉标点符号
    s = s.translate(str.maketrans('', '', string.punctuation))
    
    # 将字符串转换为小写
    s = s.lower()
    
    # 使用split()方法将字符串分割成单词列表
    words = s.split()
    
    # 创建一个空字典来存储单词及其出现次数
    word_count = {}
    
    # 遍历单词列表
    for word in words:
        # 如果单词已经在字典中，则增加其计数
        if word in word_count:
            word_count[word] += 1
        # 如果单词不在字典中，则将其添加到字典并设置计数为1
        else:
            word_count[word] = 1
    
    # 返回单词计数字典
    return word_count

# 测试示例
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.
"""
result = wordcount(text)
print(result)

运行结果为：
