How to run command from variable instead of those line in python?

Question

I have below commands for run az aks command:

from azure.cli.core import get_default_cli
az_cli = get_default_cli()
res = az_cli.invoke(['login', '--service-principal', '-u', client_id, '-p', client_secret,'--tenant',tenant_id])
az_cli.invoke(['aks','command','invoke','--resource-group',resourcegroup,'--name',clustername,'--command','kubectl apply -f',outfile_final])

I want as below,

azcmd = "az login --service-principal -u " + client_id + " -p " + client_secret + " --tenant " + tenant_id

**res = az_cli.invoke([azcmd])**

but Above script is giving error like args should be a list or tuple, and 2nd error: Is there anyways to run invoke with get input from variable.

Edit1: I'm applying deployment file as below:

namespace = "kubectl apply -f abc.yaml"

Answer 1

I tried in my environment and got below results:

Initially I tried with same command and got same error:

I installed azure-cli module in my local machine, Also instead of using -

res = az_cli.invoke([azcmd])

You can add your azcmd inside ([ ])

from  azure.cli.core  import  get_default_cli
az_cli = get_default_cli()
cmd=(['login', '--service-principal', '-u', client_id, '-p', client_secret,'--tenant',tenant_id])

res=az_cli.invoke(cmd)

Is there anyways to run invoke with get input from variable.

With above code I can invoke with get input from variable.
