time - Make python script run everyday within certain hours -

i trying make python script (infinite loop) work everyday 9am until around 23.00 , on , on again. did research , come code in end:

while true:     if dt.now().hour in range(9, 23):           if __name__ == "__main__":              """ not important """              while true:                 try:                     """ bet_automation contains necessary code """                      bet_automation()                  except exception ex:                      """ catch error of bet_automation() , restart program """                      print_error(ex)                     time.sleep(5)                     if not isinstance(ex, logintimeoutexception):                         try:                             driver = get_driver()                             filename = str(time.time())                             driver.get_screenshot_as_file("errors/{}.png".format(filename))                             io.open("errors/{}.html".format(filename)) f:                                 f.write(unicode(driver.page_source))                         except:                             pass                     try:                         quit_driver()                     except:                         pass      else:         sys.exit(0) 

by this, script manages start @ 20.00 , works correctly. if run earlier, starts working @ 20.00, great, not terminate @ 21, confusing.

i'm aware super easy , dumb question, said i'm ultimate beginner. had script programmed "professional" programmer , i'm trying edit , improve , myself understand entire process.

every insight highly appreciated,

thank much,

your code contains 2 loops. first off, outer loop. 1 irrelevant; if start program sometime between 9:00 , 23:00 dt.now().hour in range(9, 23) evaluate true, code enter inner (infinite) loop. if condition evaluates false program exit. so, outer loop body ever executed once.

then, inner loop. 1 infinite, entered code never break out of it. if on iteration bet_automation() not throw exception, executed again during next iteration. if on iteration bet_automation() does throw error, caught , handled, , loop continue.

if want code stop @ point, need build in check on current time inside inner loop, so:

while true:     try:          bet_automation()          if dt.now().hour not in range(9, 23):              break (...)
