Long string in python3-CodePudding

I am tring to run the below code in python3 running on Centos8

namespace="abcnkabc51-admin-ns"
podtype="smd"
appPodName="smd-84b4bf8fcc"
cmd_appNodeNames="kubectl get pod --show-labels -o wide -n " namespace "|egrep \"app=" podtype "\" |grep " appPodName "| awk \'{print $7}\'"
print("cmd_appNodeNames: ")
print(cmd_appNodeNames)

I am getting the printout like this-

cmd_appNodeNames: 
| awk '{print $7}'show-labels -o wide -n abcnkabc51-admin-ns|egrep "app=smd" |grep smd-84b4bf8fcc

However, expected output would be as below-

cmd_appNodeNames: 
kubectl get pod --show-labels -o wide -n abcnkabc51-admin-ns|egrep "app=smd" |grep smd-84b4bf8fcc| awk '{print $7}'

Would you please advise how can I fix this?

Regards,

Ashish

I cannot reproduce this (on Ubuntu, but that makes no difference):

The actual program is a bit complex. appPodName was an output from a pxssh function; unfortunately this value contained \r at the end. After splitting \r, I have been able to fix this.
