In python how can I find if the given time is between a range

I need to execute a code between a set time every day. So I need to find if the current time is between a time range.

hralarm=False
now = datetime.datetime.now().time()

if  datetime.time(hour=14,minute=40) > now  > datetime.time(hour=14,minute=50):
   hralarm=True
else :
   hralarm=False

The hralarm flag is always returning a False. The now variable returns 14:46:22.994000 . Should I format 'now' to not have the seconds and microseconds and maybe that is why the comparison is not happening correctly?..I am new to python so any help would be greatly appreciated.

import time
import datetime

hralarm=False
now = datetime.datetime.now().time()

time1 = datetime.time(14, 40, 0)
time2 = datetime.time(14, 50, 0)

if  (time1.hour >= now.hour and time1.minute < now.minute) and  (now.hour  <= time2.hour and now.minute  < time2.minute):
   hralarm=True
else :
   hralarm=False

print(hralarm)

You have your comparison operators mixed up. You are asking if the current time is before 14:40:

datetime.time(hour=14,minute=40) > now   # only times *smaller* will match

and after 14:50:

now > datetime.time(hour=14,minute=50)  # only times *greater* will match

No clock time can ever match both those conditions at the same time.

The following test would work to find times between 14:40 and 14:50 however:

if datetime.time(14, 40) < now < datetime.time(14, 50):
# 14:40 must be smaller          and 14:50 must be greater

Remember that the 'pointed' end of a < or > points to the smaller value.

Note that the comparison operators already produce True or False, you can assign that directly to your hralarm variable rather than use if to confirm it for you:

now = datetime.datetime.now().time()
hralarm = datetime.time(14, 40) < now < datetime.time(14, 50)
