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 执行这个bash 命令，它工作正常，所以我不打算发布那部分。

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

我将这个输出传递给一个名为output的变量

这是它的输出

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

这是我通常使用print(output) 打印时的样子

但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:                                                                                                                                                                                    
             ● - akamai-1576227900-wrkct               Completed

vault-renew-tokens-1576378800-6dp98             Completed

它没有正确对齐。

我真正想要的是这样的：

???? - here is the output:                                                                                                                                                                                   
             ● - akamai-1576227900-wrkct         Completed
                 akamai-1576314300-xhf78         Completed                                                                                                                                                                          
                 akamai-1576400700-6m84q         Completed
                 akamai-1576487100-bnrg7         Completed

                 akamai-1576659900-npb6g         Completed
                 akamai-1576746300-6vdjm         Completed

我该怎么做？

我正在考虑将bash 命令输出到一个数组，以便我可以正确执行此操作，但我无法将输出输出到array

有什么好的方法可以做到这一点？

无需使用python，只需通过管道将其发送到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
