I’ve told this to a few people already.
If you are interested in all-round development I would totally recommend Python as it is readable and really easy to understand with a lot of expandability due to the wide variety of available library’s.
Those will teach you the basics of front-end web development.
You can then use your python knowledge to do some back-end stuff.
There are more languages and I should not be the one to give these kinds of advice.
I got into programming only 3 years ago.
I wish you a lot of luck on your coding journey!
