when throw script, shows in terminal list of urls parsed in "image_urls."

{'image_urls': [u'https://thehackerway.files.wordpress.com/2017/04/1.png?w=595&h=382',             u'https://thehackerway.files.wordpress.com/2017/04/2.png?w=595&h=327',...}

(side note: core of problem entanglement of user input firing “expensive computations”. therefore, cannot separate both in 2 scripts, , letting 1 spawning other daemon.) the command screen may you. use screen -l create new session , run application. after inputting data, can press " ctrl-a " , press " d " on keyboard detach session. now...
