How to Build Timedelta Objects from Strings in Python with datetime?

Constructing Timedelta Objects from Strings with Python's datetime

Manipulating timestamps and time intervals often requires parsing user-provided strings into timedelta objects. To simplify this task, Python's datetime library offers a versatile solution.

The Power of dateutil's strptime

Python's datetime module includes the strptime method, which allows for precise parsing of string representations of dates and times. This method enables you to define custom formats and extract specific time components efficiently.

An Elegant Approach Using strptime and timedelta

To construct a timedelta from a simple string, you can leverage the strptime method in combination with timedelta properties:

<code class="python">from datetime import datetime, timedelta
# Specify the format and parse the string...
t = datetime.strptime("05:20:25", "%H:%M:%S")
# ...and use properties to build the timedelta
delta = timedelta(hours=t.hour, minutes=t.minute, seconds=t.second)</code>

This approach elegantly handles various time formats, such as "05:20:25" or "2:32". You can then use the constructed timedelta as needed, calculating total seconds or performing time-related calculations.
