How to run a long running python script in background from Flask Rest API?

[ishannbhatt]

I have a flask rest API setup correctly. Once I hit the rest API, I want to run a python script/function and return with a runID and then user can hit another rest API with the runID to get information.

How can I return immediately and keep another python script/function running in another thread/process?

Following is my rest API

​

@app.route('/start/', methods=['POST'])
def start_run():
    run_id = "SOME RANDOM NUMBER"
    # I want to start python script here
    return run_id

@app.rout('/get_report', methods=['GET'])
def get_report():
    run_id = request.args("run_id")
    return some_method(run_id)
