问题描述
当我尝试在 nxos 设备上运行一些命令时,输出的末尾有一个空格.我必须将输出与现有的变量列表进行比较.最后的空格导致比较失败.如何在字符串列表中使用 .strip() 函数?
When I try to run some commands on nxos devices, the output has a white space at the end. I have to compare the output to an existing variable list. The whitespace at the end is causing the comparison to go false. How to make use of .strip() function in a list of strings?
- name: Current TACACS server host before
nxos_command:
commands:
- sh run | include 'tacacs-server host'
register: runconfserafter
- debug:
var: runconfserafter
输出结果如下:
"stdout_lines": [
[
"tacacs-server host 1.1.1.1 key 7 \"HelloWorld\" ",
"tacacs-server host 2.2.2.2 key 7 \"HelloWorld\""
],
]
当我将这一行与我想要的变量进行比较时,由于第一行末尾的空格,我无法将其匹配.
When I compare this line with my desired variables, I can't get it matched because of the white space on the first line at the end.
推荐答案
要应用函数来列出元素,请使用 map
过滤器.要去除空格,请使用 trim
过滤器.>
To apply a function to list elements use map
filter. To strip whitespace use trim
filter.
"{{ runconfserafter.stdout_lines | map('trim') | list }}"
