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。

代码如下

def word_count(input_sentence):
    words = re.split(r'[,\s.;\n]+', input_sentence.lower())
    #print(words)
    word_dict = {}
    rdcount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。
    for word in words:
        if len(word) == 0:
            continue
        if word == 'i':
            word = 'I'
        if word in word_dict:
            word_dict[word] += 1
        else:
            word_dict[word] = 1
    
    return word_dict


if __name__ == '__main__':
    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.
    """ 
    res = word_count(text)
    print(res)

运行结果
