How can I change microseconds in a datetime?

How can I change my code to new output?

My code:

import datetime
x = datetime.datetime.today()
print(x) 
# Old Output: 2021-12-15 12:03:16.151803 

but I want to create new output (remove the 803 from 12:03:16.151803 and save whole new output 2021-12-15 12:03:16.151)

# New Output: 2021-12-15 12:03:16.151

>Solution :

The simplest way to do that is by slicing it

Example:

x = datetime.datetime.today().strftime("%Y-%m-%d %H:%M:%S.%f")[:-3]
print(x)
