Python 3.x 仅当python中的两行连续行开始时合并，并正常写入其余文本

输入

代码

您好，我有一个代码，搜索两个连续的行是否从03110开始并打印这些行，但我想转换代码，以便它打印或在.txt处写入其余行

输出应该是这样的

prev = ''
with open('out.txt') as f:
    for line in f:
        if prev.startswith('03110') and line.startswith('03110'):
            print(prev.strip()+ '|03100|XX|PARCELA|' + line)
        prev = line

我知道我只合并了这两行，因为这是print（）的命令

---

但是我不知道如何进行desire输出，有人能帮我编写代码吗？

您的代码加入行，但我得到了第一行03110的重复行。您的代码加入行，但保留前03110，我希望喜欢输出。我说清楚了吗？你能帮我吗？好的，现在应该可以了。我忘了添加

elif语句
