python - How can I continuously check the hour within a while loop? -


this first post , first project in python. i'm trying control hardware sensor through number of conditions:

  1. if sensor senses movement, send e-mail , sleep
  2. elif time range not between work hours, sleep until 9am
  3. else sleep half second , wait sensor

so far first condition , last condition work. is, if there no movement, repeat sleep(0.5) until sensor activates.

issue: i'm having trouble middle portion time not between 9-5. if run code before 9 or after 5, sleeps until 9am arrives intended, if code running between 9-5 (waiting movement), middle condition never triggers. gets stuck on sleep(0.5).

i'm not experienced have vague idea second process should keep track of time. suggestions? here code.

def pir_init():     while true:         m = datetime.datetime.now().time().minute   #loop through current time         h = datetime.datetime.now().time().hour              if h < 9:                                                        print("sleeping...")             time_sleep = (9 - h) * 3600             time.sleep(time_sleep)         elif h > 16:             print("sleeping...")             time_sleep = ((24 - h) + 9) * 3600             time.sleep(time_sleep)         elif io.input(pir_pin):             print("pir alarm")             send_gmail()                time.sleep(10)      #cooldown prevent email spew         else:             print "waiting..."             time.sleep(0.5)     #sleep , wait movement             print m     print "loop end"   # main if time_elements[0] > '0' , time_elements[0] < '6':  #weekdays     if get_hour > 8 , get_hour < 17:             #hour range         pir_init()     elif get_hour > 16:         print("initialization @ 9am...")         time_sleep = ((24 - get_hour) + 9) * 3600         time.sleep(time_sleep)         pir_init()              #initiate sensor     elif get_hour < 9:         print("initialization @ 9am...")         time_sleep = (9 - get_hour) * 3600         time.sleep(time_sleep)         pir_init() else:     #to completed     print time_elements[0]     print "bad weekday"

you have update time_elements inside while loop, program uses current time in condition test if shall sleep until 9a.m. otherwise, if don't update time_elements inside while loop, if program didn't enter in condition in first time, never enter.

that explains behavior noticing; in fact, definition of time_elements isn't shown here...

Why does Ruby on Rails generate add a blank line to the end of a file? -

running rails generate controller foo home results in: class foocontroller < application controller def home end end (there's nothing on line in actual file, blank line) is there purpose blank line? it's common use newline indicate end of line, last line. many editors (like vi, use) add in newline silently. consensus text files (especially in unix world) should end in newline, , there have been problems historically if wasn't present. why should text files end newline? the tool used count lines in file "wc" counts newlines in file, without trailing newline show 3 instead of 4. it improves readability of templates used in generator. consider: https://github.com/rails/rails/blob/master/railties/lib/rails/generators/rails/controller/templates/controller.rb to remove trailing newline, template have last line of: end<% end -%> instead of: end <% end -%> that seems less readable me. the discussion below refers
