Datetimefromisoformat

Datetimefromisoformat is a method in Python's datetime module that parses a string representing a date and time in ISO 8601 format and returns a datetime object. ISO 8601 is an international standard that defines the format for date and time representations. The method is particularly useful for converting strings that adhere to this standard into datetime objects, which can then be manipulated or formatted as needed.

The method takes a single argument, which is the ISO 8601 formatted string. The string can include date, time, and timezone information. The date part is mandatory, while the time and timezone parts are optional. The method supports various ISO 8601 formats, including basic and extended formats, as well as different levels of precision for time.

For example, the string '2023-10-05T14:48:00' represents a date and time in the extended format, and '20231005T144800' represents the same date and time in the basic format. Both of these strings can be parsed using datetimefromisoformat to create a datetime object.

The method is part of the datetime class and can be accessed as datetime.datetime.fromisoformat(). It is available in Python 3.7 and later versions. The method raises a ValueError if the input string does not conform to the ISO 8601 format.
