Convert datetime to String without Microsecond Component in Python (3 Examples)


On this site, you’ll learn how to convert a datetime object to a string without a microsecond component in the Python programming language.

The following sections are explained in this article:

Let’s do this!


Importing datetime module & Creating Example Data

First, we have to import the datetime module:

from datetime import datetime

Next, we can create an example datetime object using the now() function as shown below:

my_datetime =
# 2021-11-19 07:22:34.542583

Our example date is the 19th of November 2021 at 07:22:34am. As you can see, our example datetime object also contains a milliseconds and microseconds component showing the value 542583.

Let’s convert our datetime object to a character string without these microseconds!


Example 1: Remove Microseconds from datetime Object Using isoformat() Function

This example uses the isoformat() function of the datetime module to delete the milliseconds and microseconds from our datetime object.

This method takes a datetime object and returns a character string representing the date in ISO 8601 format.

To get rid of the microseconds component, we have to specify the keyword ‘seconds’ within the isoformat function.

my_string1 = my_datetime.isoformat(' ', 'seconds')
# 2021-11-19 07:22:34


Example 2: Remove Microseconds from datetime Object Using replace() Function

This example uses the replace() function to create a string object without microseconds:

my_string2 = my_datetime.replace(microsecond = 0)
# 2021-11-19 07:22:34


Example 3: Remove Microseconds from datetime Object Using str() & slice() Functions

Another approach to exclude microseconds from a datetime object is based on the str() and slice() functions.

The str() function converts a datetime object into a string with microseconds.

The slice function can be applied to this string to return only the first 19 characters. This deletes the last part of the string, i.e. the microseconds component.

my_string3 = str(my_datetime)[:19]
# 2021-11-19 07:22:34
