python 任务编排

1... 目的,一坨坨的函数选择执行...

2...code

# file m.py
from obj.tsk import Task
from obj.acc import Acc

map_name_cls = {"task": Task, "acc": Acc}

fconf = [
    {"task_type": "task",
     "task_list": ["task", "pre_task", "lf"]},
    {"task_type": "acc",
     "task_list": ["task", "pre_task", "lf"]}
]

if __name__ == '__main__':
    for k in fconf:
        tsk_type = k["task_type"]
        tsk_list = k["task_list"]
        cls = map_name_cls[tsk_type](tsk_list)
        for ts in tsk_list:
            run_flag = True
            try:
                func = getattr(cls, ts)
            except:
                run_flag = False
            if run_flag:
                func()

file obj/acc.py 和tsk.py类同
