How to use strptime with milliseconds in Python
strptime() function in python converts the string into DateTime objects. The strptime() is a class method that takes two arguments :
- string that should be converted to datetime object
- format string used to parse the string.
These two string arguments are mandatory for converting a string into DateTime object.

To use this function to produce milliseconds in python %f is used in format code.
Given below are some implementations.
Example 1: Time with milliseconds
Python3
from datetime import datetime
datetime_string = "15/06/2021 13:30:15.120"
print ( type (datetime_string))
format = "%d/%m/%Y %H:%M:%S.%f"
date_object = datetime.strptime(datetime_string, format )
print ( "date_object =" , date_object)
print ( type (date_object))
|
Output:
<class 'str'>
date_object = 2021-06-15 13:30:15.120000
<class 'datetime.datetime'>
Example 2: time with milliseconds
Python3
from datetime import datetime
date_str = str (datetime.now())
print ( type (date_str))
print (datetime.strptime(date_str, '%Y-%m-%d %H:%M:%S.%f' ))
|
Output:
<class 'str'>
2021-08-01 15:27:59.979673
Example 3: time with milliseconds
Python3
from datetime import datetime
date_time = datetime.strptime(
"17 Oct 2021 15:48:35.525001" , "%d %b %Y %H:%M:%S.%f" )
print (date_time)
|
Output:
2021-10-17 15:48:35.525001
