Have a program to get a date count down. I don't want to print the milliseconds, please help here is my program in python:
import time
import datetime
while (datetime.datetime.now() != datetime.datetime (2018,5,5,19,30)):
print (datetime.datetime (2018,5,5,19,30) - datetime.datetime.now())
time.sleep(1.0)
This is my current output: 54 days, 3:54:53.603289
Would like: 54 days, 3:54:53, but don't know how to do it.
You are looking for datetime.replace(microsecond=0), which will:
Return a datetime with the same attributes, except for those attributes given new values by whichever keyword arguments are specified.
import time
import datetime
while (datetime.datetime.now() != datetime.datetime (2018,5,5,19,30)):
print (datetime.datetime (2018,5,5,19,30) - datetime.datetime.now().replace(microsecond=0))
time.sleep(1.0)
Output:
54 days, 3:49:31
54 days, 3:49:30
54 days, 3:49:29
54 days, 3:49:28
54 days, 3:49:27
54 days, 3:49:26
54 days, 3:49:25
54 days, 3:49:24
54 days, 3:49:23
As you have found, there are no good formatting options for a timedelta object. I would recommend you pre-calculate an end_time and also use < rather than waiting for the times to match. In the event your PC is busy at the exact second, your loop might miss the match. By using < it will also catch it:
from datetime import datetime
import time
end_time = datetime(2018, 5, 5, 19, 30)
while datetime.now() < end_time:
print(end_time - datetime.now().replace(microsecond=0))
time.sleep(1.0)
