python3 - how to Simplifying multiple if/else statements

Question

Using more than one nested if/else makes the logic bloated.

How can I simplify the following code.

The more than one nested if/else format and logic is pretty ugly.

payload_dict = {"process": None, "status": None, "taskId": task_id,
 "jenkinsJobName": job_name, "msg": None}
if srv_result == "failed":
 if result:
 logging.info("srv start failed")
 response_data = {"errorMsg": "failed", "errorCode": "2", "serviceList": result}
 _msg = json.dumps(response_data, ensure_ascii=False)
 payload_dict.update(process=1, status=0, msg=_msg)
 logging.info(f"Requests:{payload_dict}")
 else:
 logging.info("srv start failed")
 response_data = {"errorMsg": "failed", "errorCode": "2",
 "serviceList": "srv start failed"}
 _msg = json.dumps(response_data, ensure_ascii=False)
 payload_dict.update(process=1, status=0, msg=_msg)
 logging.info(f"Requests:{payload_dict}")
else:
 if result:
 logging.info(f"failed srv:{result}")
 response_data = {"errorMsg": "failed", "errorCode": "1", "serviceList": result}
 _msg = json.dumps(response_data, ensure_ascii=False)
 payload_dict.update(process=1, status=0, msg=_msg)
 logging.info(f"Requests:{payload_dict}")
 else:
 logging.info("deploy success.")
 response_data = {"errorMsg": "sucess", "errorCode": "0", "serviceList": result}
 _msg = json.dumps(response_data, ensure_ascii=False)
 payload_dict.update(process=1, status=1, msg=_msg)
 logging.info(f"Requests:{payload_dict}")

• PeterM: Refractor it into methods handling results. The problem here are not nested conditions, but repetitive code.

A bit improved.

payload_dict = {"process": None, "status": None, "taskId": task_id, "jenkinsJobName": job_name, "msg": None}
stat = 0
if srv_result == "failed" and result:
 logging.info("srv start failed")
 response_data = {"errorMsg": "failed", "errorCode": "2", "serviceList": result}
elif srv_result == "failed":
 logging.info("srv start failed")
 response_data = {"errorMsg": "failed", "errorCode": "2", "serviceList": "srv start failed"}
elif result:
 logging.info(f"failed srv:{result}")
 response_data = {"errorMsg": "failed", "errorCode": "1", "serviceList": result}
else:
 logging.info("deploy success.")
 response_data = {"errorMsg": "sucess", "errorCode": "0", "serviceList": result}
 stat = 1
_msg = json.dumps(response_data, ensure_ascii=False)
payload_dict.update(process=1, status=stat, msg=_msg)
logging.info(f"Requests:{payload_dict}")
