如何从一个文本文件创建对，该文本文件是一个数字和该数字前面的单词？

def create_pairs_from_text_file(file_path):
    pairs = []
    with open(file_path, 'r') as file:
        text = file.read()
        words_and_numbers = text.split()
        for i in range(1, len(words_and_numbers)):
            if words_and_numbers[i].isdigit():
                pair = (words_and_numbers[i], words_and_numbers[i-1])
                pairs.append(pair)
    return pairs

file_path = 'example.txt'  # 替换为实际的文本文件路径
pairs = create_pairs_from_text_file(file_path)
print(pairs)
