如何在字符串中的单词a之间交换和重新克隆

def swap_and_clone_words_between_a(string):
    # Step 1: Split the string into word array
    words = string.split()

    # Step 2: Find positions of words containing 'a'
    positions = [i for i, word in enumerate(words) if 'a' in word]

    # Step 3: Swap words between 'a'
    for i in range(len(positions)-1):
        start = positions[i] + 1
        end = positions[i+1]
        words[start:end] = words[start:end][::-1]

    # Step 4: Clone words between 'a'
    cloned_words = words[:]

    return ' '.join(cloned_words)

# Example usage
string = "This is a sample string to demonstrate swapping and cloning words between 'a'"
result = swap_and_clone_words_between_a(string)
print(result)
