I need to get number of Pods in a Kubernetes Cluster with kubernetes python client

i have a code to get the number of Pods it give the output but it loads too many unwanted data in (ret_pod), is there a better way to do it?

from  kubernetes import client , config 

config.load_kube_config()
v1= client.CoreV1Api()
ret_pod = v1.list_pod_for_all_namespaces(watch=False)
print(len(ret_pod.items))

which gives me the output of

kubectl get po -A -o json 

and then finds the length. but i just want to do the output of

kubectl get po -A
