书生大模型实战营闯关记录----第二关：实现word_count统计文本中word频次

实现word_count统计文本中word频次

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': 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.
"""

实现代码：

def wordcount(text):texts = [t.lower() for t in text.replace('\n', ' ').replace(',', '').replace('.', '').strip().split(' ')]map_count = {}for t in texts:if t==" " or t=='': continueif t not in map_count: map_count[t]=0map_count[t]+=1return map_countif __name__=="__main__":text = """

"""count = wordcount(text)print(count)

运行结果为：
