如何通过行而不是变量中的字符进行for-loop循环？

Question

我有以下代码ssh到一个节点，并找到其他设备的RSSIs。

bot_ipv6是一个ipv6地址列表ssh到和脚本使用pexpect到ssh。

for address in bot_ipv6: 
    session=spawn('ssh -6 root@'+address+'%wlan0') 
    #session.logfile = stdout 
    session.expect('password:') 
    session.sendline("123456") 
    session.expect(prompt) 
    session.sendline("iwlist wlan0 scan") 
    session.expect(prompt) 
    data=session.before 
    session.close() 

数据现在在该设备上包含iwlist wlan0 scan的输出。

我想查看数据并获取地址及其对应的RSSI。此代码的工作时，该命令可以在本地运行并输出到文件：

with open("rssi.txt") as fd: 
    for line in fd: 
     cell_line = match(line,"Cell ") 
     if cell_line != None: 
      cells.append([]) 
      line = cell_line[-27:] 
     cells[-1].append(line.rstrip()) 


for cell in cells: 
    level.append(matching_line(cell,"Quality=").split()[2].split('=')[1]) 
    address.append(matching_line(cell,"Address: ")) 

scanned=dict(zip(address, level)) 

在哪里比赛和匹配线的功能定义别的地方那样子在该文件中匹配的字符是什么期待的。

我的问题是，我不知道如何将数据输出到文件，但如果我尝试去通过lineds输出数据，因为我使用的文件时做到：

for line in data: 
     cell_line = match(line,"Cell ") 
     if cell_line != None: 
      cells.append([]) 
      line = cell_line[-27:] 
     cells[-1].append(line.rstrip()) 

代替线，它循环通过每个字符。

如何将输出结果打印到一个文件中，我可以像本人那样在本地打开并扫描文件，或者通过循环显示数据而不是单个字符？

这里是一个什么数据看起来像一个样品（得到它，我把打印数据到脚本，然后就从输出这里复制并粘贴它，幸而没有格式会丢失）：

使用str.splitlines将字符串分割成线：

for line in data.splitlines(): 
    # Do things.
