我没有达到我想要的方式，有什么帮助吗？第一列始终有一个MP数据，每行有13个管道作为分隔符

编辑：

下面我试着用“MP”而不是“D | 1”来做同样的事情，但没有给出正确的结果，因为有些行没有“D | 1”，在末尾有类似的“U | 1234”

content = ([l.strip().decode('utf-8') for l in s1 if l.strip()])

for line in content:
    find_START = line.find('MP')   # check if line has D|1
    if find_START ==0:
       tmp += line
       res.append(tmp)
       tmp = ''
    else:
     tmp += line

for r in res:
    print(r)
其印刷如下：
