从 ansible 输出中删除 u'

Question

运行我的剧本得到的输出有问题。如何将调试输出H/W Version : 1.0转换为HW Version: 1.0

以及如何清理输出文件以删除u'和[]

more /tmp/sw-facts

Hostname: switch Version: 5.2(1)N1(3) Hardware: [u'H/W Version : 1.0'] Serial: 000000000

提前感谢您对的帮助

Answer 1

我将nxos_command修改为："show sprom sup|inc'H/W Version'|cut-c 19-22">

Answer 2

问题来自于使用Python 2。如果不能切换到Python3，可以使用to_yaml过滤器，因此您的输出看起来像：[H/W Version : 1.0]。
