script.functionABC()

//parse prev json response data
import groovy.json.JsonSlurper;
def jsonSlurper = new JsonSlurper();
def response = jsonSlurper.parseText(prev.getResponseDataAsString());
vars.put("responData", response.responData.toString());
log.info("responData:" +  vars.get("responData"));
vars.put("key1", response.responData.key1.toString());
log.info("key1:" + vars.get("key1"));

//define global param
import groovy.transform.Field;

//run conda command to execute python script in jmeter groovy script
'cmd /c activate base && cd C:/folder && python test.py key1_split_value1 key2_split_value2 && conda deactivate'.execute()

# use below code in python project, split vars from jmeter
options = []
split_str = '_split_'
n = len(sys.argv)
for i in range(1, n):
    k = sys.argv[i].split(split_str)[0]
    v = sys.argv[i].split(split_str)[1]
    options[k] = v
    print(k)
    print(options.get(k))
