Parsing ISO 8601 Datetime Strings in Python

Many applications encounter datetime strings in the ISO 8601 format, such as "2009-05-28T16:15:00." Historically, users have employed a "hackish" approach, utilizing time.strptime to parse the string and create a datetime object.

However, there are more efficient and reliable methods available.

dateutil Library

The dateutil library provides a comprehensive set of datetime handling functions, including parsing ISO 8601 strings. Its usage is as follows:

from dateutil import parser
yourdate = parser.parse(datestring)

This approach handles various ISO 8601 formats, including those with timezones, making it a preferred choice for complex datetime parsing tasks.
