如何在删除一行后删除文本文件末尾的空行？

def delete_line_and_trailing_empty_lines(file_path, line_number):
    # 读取文本文件内容
    with open(file_path, 'r') as file:
        lines = file.readlines()
    
    # 删除指定的行
    if line_number <= len(lines):
        del lines[line_number - 1]
    
    # 检查连续的空行并记录行号
    empty_line_start = -1
    for i, line in enumerate(lines[line_number - 1:]):
        if line.strip() == '':
            if empty_line_start == -1:
                empty_line_start = line_number + i
        else:
            if empty_line_start != -1:
                break
    
    # 删除连续的空行直到文件末尾
    if empty_line_start != -1:
        del lines[empty_line_start - 1:]
    
    # 将修改后的内容写入原始文本文件
    with open(file_path, 'w') as file:
        file.writelines(lines)
