python - 如何使用 python 对齐 linux 输出

Question

我正在尝试对齐 bash 命令的输出。

这是我现在使用的命令。我使用 python 执行此 bash 命令，它运行良好，因此我不会发布该部分。

kubectl get pods -n kube-system | awk '/Completed/ {print $1}'

我将此输出发送到一个名为output

的变量

这就是它的输出

akamai-1576314300-xhf78         Completed                                                                                                                                                                          
akamai-1576659900-npb6g         Completed
akamai-1576746300-6vdjm         Completed
keycloak-setupbhnhc-zskhw               Completed
vault-renew-tokens-1576378800-6dp98             Completed

这就是我通常使用 print(output) 打印它时的样子

但是我正在像这样使用这个output变量。

print("here is the output: "+constant.ICON+output+")

我的输出现在看起来像这样:

👎 - here is the output:

未正确对齐。

我真正想要的是这样的:

                 akamai-1576746300-6vdjm         Completed

我该怎么做？

我正在考虑将 bash 命令输出保存到数组中，以便我可以正确执行此操作，但我无法将输出保存到数组

有什么好的方法可以做到这一点吗？

Answer 1

无需使用python，只需将其通过管道传输到column -t:

kubectl get pods -n kube-system | awk '/Completed/ {print $1}' | column -t

例如

$ cat file.txt
akamai-1576314300-xhf78         Completed                                                                                                                                                                          
akamai-1576659900-npb6g         Completed
akamai-1576746300-6vdjm         Completed
keycloak-setupbhnhc-zskhw               Completed
vault-renew-tokens-1576378800-6dp98             Completed
