统计多个单词的单词出现次数的问题

def count_word_occurrences(text):
    # 将文本转换为小写，并去除标点符号
    text = text.lower()
    text = text.replace(",", "").replace(".", "").replace("!", "").replace("?", "")

    # 将文本分割成单词列表
    words = text.split()

    # 创建一个空字典，用于存储单词及其出现次数
    word_counts = {}

    # 遍历单词列表，统计每个单词的出现次数
    for word in words:
        if word in word_counts:
            word_counts[word] += 1
        else:
            word_counts[word] = 1

    # 返回单词及其出现次数的字典
    return word_counts

# 测试代码
text = "This is a sample text. It contains multiple words, some of which may repeat."
result = count_word_occurrences(text)
print(result)
