Wayne's suggestions are good. Some folks enjoy learning from videos. Others prefer seeing text. In addition to the w3schools.com that Wayne mentioned, the Python web site itself has help and tutorials for beginners. For an overview to help you get started, https://www.python.org/about/gettingstarted/
is a good place to look. To go directly to a tutorial, https://docs.python.org/3/tutorial/
is the place to start.
May I also suggest that you start your learning with modern Python (Python 3)? There are older versions of Python still available, but all of them will be "end-of-lifed" next year. Although there are numerous videos, books, web sites, etc. that use Python 2, please keep looking for an equivalent in modern Python.
