如何通过行而不是变量中的字符进行for循环？

Question

我有以下代码可以SSH到节点并从其他设备中找到RSSI。

bot_ipv6是ssh到的ipv6地址的列表，脚本使用pexpect来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()

数据现在包含该iwlist wlan0 scan设备的输出。

我想浏览数据并仅获取地址及其对应的RSSI。当命令可以在本地运行并输出到文件时，此代码有效：

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))

匹配和匹配行是在其中定义的函数，在其他地方则在文件中查找以将字符与所要查找的字符进行匹配。

我的问题是我不知道如何将数据输出到文件，但是如果我尝试像使用文件时那样遍历输出数据中的行：

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

而不是线条，它循环遍历每个字符。

如何将输出打印到可以像以前一样在本地打开并扫描的文件，或者循环遍历数据中的行而不是单个字符？

以下是数据外观的示例（要获得此数据，我将打印数据放入脚本中，然后从输出中复制并粘贴到此处，希望不会丢失任何格式）：

Answer 1

使用str.splitlines一个字符串分割成几行：

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