how to write API query with filters in prometheus

what I want: get the metrics from Prometheus with python

sample code here:

import requests
url='prometheus.cup.com'
response=requests.get("{0}/api/v1/query_range?query=container_cpu_load_average_10s&start=2018-11-05T00:59:00.781Z&end=2018-11-05T01:00:00.781Z&step=15s".format(url))

sample result is:

{u'beta_kubernetes_io_os': u'linux', u'name': u'k8s_POD_nginx-bf8f468d8-gbjvp_openwhisk01_01f85b0c-9f87-11e8-893e-6c92bf025c32_5', u'image': u'openshift/origin-pod:v3.9.0', u'namespace': u'openwhisk01', u'instance': u'openshift-app1.cup.com', u'job': u'kubernetes-cadvisor', u'pod_name': u'nginx-bf8f468d8-gbjvp', u'container_name': u'POD', u'__name__': u'container_cpu_load_average_10s', u'beta_kubernetes_io_arch': u'amd64', u'id': u'/kubepods.slice/kubepods-besteffort.slice/kubepods-besteffort-pod01f85b0c_9f87_11e8_893e_6c92bf025c32.slice/docker-d7422ab03a96a07395538e5fa5c9d971bb66855f94a45f4540f423cb1da3422f.scope', u'kubernetes_io_hostname': u'openshift-app1.cup.com'}

problem: i want to get result by some filters, like

query=container_cpu_load_average_10s{container_name=POD}, 
(of course, this type is not right, just an example)

so what's the right method to write the API query with filters in python?

thanks in advance

Oliver answer have some error, fix it. 

#!/usr/bin/env python

import requests

prome_sql = "(node_memory_MemTotal_bytes - (node_memory_MemFree_bytes + node_memory_Buffers_bytes + node_memory_Cached_bytes)) / node_memory_MemTotal_bytes * 100"

response = requests.get('http://192.168.20.249:9090/api/v1/query',
    params={'query': prome_sql})
print(response.json()["data"]['result'])

Your code is almost correct, just pass the query as a parameter to the URL. See this abbreviated snippet of code taken from here:

response = requests.get('http://localhost:9090/api/v1/query'),
    params={'query': "query=container_cpu_load_average_10s{container_name=POD}"})
print(response.json()['data']['result'])
