当两个文件中的行数不同时，根据另一个文件的匹配值在变量中添加行号索引

# 读取两个文件的内容
with open('file1.txt', 'r') as file1:
    content1 = file1.readlines()

with open('file2.txt', 'r') as file2:
    content2 = file2.readlines()

# 确定较少行数的文件
if len(content1) < len(content2):
    shorter_content = content1
    longer_content = content2
else:
    shorter_content = content2
    longer_content = content1

# 遍历较少行数的文件，提取匹配值并在变量中添加行号索引
result = []
for index, line in enumerate(shorter_content):
    match_value = line.strip()  # 假设匹配值在每行的末尾，去除行尾的换行符
    for i, long_line in enumerate(longer_content):
        if match_value in long_line:
            result.append((index+1, long_line.strip()))  # 添加行号索引和匹配行内容

# 输出结果
for line_index, line_content in result:
    print(f"行号索引：{line_index}，匹配行内容：{line_content}")
