Python实现wordcount

import string
def wordcount(text):
     # 去除标点符号
    translator = str.maketrans('', '', string.punctuation)
    text = text.translate(translator)
    
    # 将所有单词转换为小写
    text = text.lower()
    
    # 将文本分割为单词列表
    words = text.split()
    
    # 统计每个单词出现的次数
    ans={}
    for word in words:

        if word not in ans:  
            ans[word] = 1  
        else:  
            ans[word] += 1  
    return ans  
text = """Hello world!    
This is an example.    
Word count is fun.    
Is it fun to count words?    
Yes, it is fun!"""  
res = wordcount(text)  
print(res)

结果

{'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}
