Apr 2, 2022 · The code specific to format milliseconds is: {dt.microsecond // 1000:03d} The format string {:03d} and microsecond to millisecond conversion // 1000 is from def _format_time in https://github.com/python/cpython/blob/master/Lib/datetime.py that is used for datetime.datetime.isoformat().

Unfortunately, Python`s doesn't have a directive for milliseconds, just microseconds (see doc), but you can workaround it by appending three zeros at the end of the string and parsing the string as microseconds, something like:

Apr 17, 2025 · The strptime() method from the datetime module in Python helps convert string representations into datetime objects. To include milliseconds while parsing time, the %f format code is used.

Dec 20, 2016 · You need to provide an appropriate format string to datetime.datetime.strptime. See the docs. In Python 3 this can be done in 2 steps: Multiply the timestamp of the datetime object by 1000 to convert it to milliseconds. For example like this: '%d.%m.%Y %H:%M:%S,%f') Output: strptime accepts your timestring and a format string as input.

Feb 2, 2024 · This tutorial will cover how to convert a datetime object to a string containing the milliseconds. Use the strftime() Method to Format DateTime to String. The strftime() method returns a string based on a specific format specified as a string in the argument.

Dec 5, 2024 · If you are using Python 3.6 or a later version, the simplest way to format a datetime object to a string with milliseconds is to leverage the isoformat method. You can specify the timespec argument to achieve the required level of detail. ## Format current UTC time formatted_time = datetime.utcnow().isoformat(sep=' ', timespec='milliseconds')

Dec 18, 2022 · Converting a datetime object to a string with milliseconds in Python 3 can be achieved using the strftime() method. By specifying the format string “%Y-%m-%d %H:%M:%S.%f”, the milliseconds can be included in the resulting string representation of …

Nov 25, 2021 · In this example, we’ll use the strftime() function to convert a datetime object to a character string with milliseconds and microseconds. More precisely, we’ll use the format ‘%Y-%m-%d %H:%M:%S.%f’ (i.e. years, months, days, hours, minutes, seconds, and milliseconds).

Oct 13, 2023 · To use strptime () with milliseconds, we need to follow a two-step process: Parse the string without milliseconds using strptime (). Extract the milliseconds separately and add them to the parsed datetime object. Import the datetime module. Define the input string representing the date and time with milliseconds.

Apr 25, 2025 · To format a datetime object to include milliseconds, you can use the strftime method. The format string %f is used to represent microseconds, which can be adjusted to show milliseconds by slicing the string. Here’s how you can do it: This code snippet demonstrates how to format the current datetime to include milliseconds.
