如何打印单词的重复次数

def count_word_occurrences(sentence):
    words = sentence.split()  # 将句子拆分成单词列表
    word_count = {}  # 用字典来保存每个单词的出现次数

    for word in words:
        if word in word_count:
            word_count[word] += 1
        else:
            word_count[word] = 1

    for word, count in word_count.items():
        print(f"The word '{word}' appears {count} times.")

# 示例用法
sentence = "I love programming. Programming is fun!"

The word 'love' appears 1 times.
The word 'programming.' appears 1 times.
