error when executing the program python - 


def main():    get_value =get_display_info('5 6 0','7 0 0 0 5')    print(get_value)  def get_display_info(dice_to_roll_again_str, dice_set_aside_str):       length1 =len(dice_to_roll_again_str)    d = dice_set_aside_str    if dice_set_aside_str == none:      return 0    else :      return len(dice_set_aside_str)    if length1 , dice_set_aside_str  > 0:      return "(dice roll again:" + str(dice_to_roll_again_str) +','+                "dice set aside:" + str(d) + ')'    elif length1 > 0:      return "(dice roll again:" + str(dice_to_roll_again_str) + ')'    elif dice_set_aside_str > 0:      return "(dice set aside:" + str(d) + ')'

why program stop executing upon reaching statement? 

if length1 , dice_set_aside_str > 0:

your code return unconditionally after block:

def get_display_info(dice_to_roll_again_str, dice_set_aside_str):       length1 =len(dice_to_roll_again_str)    d = dice_set_aside_str    if dice_set_aside_str == none:      return 0    else :      return len(dice_set_aside_str)

command line - How can a Python program background itself? -

consider following python command-line program. doesn't work because incomplete, think illustrates problem: #!/usr/bin/python3 import multiprocessing pool = multiprocessing.pool() task in expensive_iterator_with_user_interaction(): pool.call_async(expensive_computation, (task,)) pool.close() print("dear user, may press ctrl-z , bg script.") pool.join() thus, problem scripts needs user input while it's launching expensive parallel processes. there moment when user interaction not needed anymore. then, ask user background process shell actions. however, can achieved program itself? (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...
