我尝试过：

f=open('C:/Users/user/Desktop/a.csv','r')
lines=f.readlines()
mystr = '|'.join([line.strip() for line in lines])
print(mystr)

我没有达到我想要的方式，请帮忙吗？第一列始终具有MP数据，每行有13个管道作为分隔符。

编辑：

如何用找到的'MP'而不是'D | 1'做同样的事情，下面是我尝试过的方法，但是没有给出正确的事情，因为有些行没有'D | 1 ”，并且结尾处带有“ 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)

其打印如下：

因此：

res = []             # empty list to store the results
tmp = ''             # empty string for unindented lines
with open(logFile) as f:
    content = f.readlines()

# you may also want to remove empty lines
content = [l.strip() for l in content if l.strip()]

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

for r in res: print(r)

输出：
