What kind of programming do you want to do? If it is front end, HTML is the place to start.
Although keep in mind that neither HTML or CSS (which goes along HTML) isn’t programming. One is a markup language (HTML), other is simply for styling things (CSS).
Keep in mind that they’re all very interchangable and can be used for many more purposes than listed. For example, python can also be used for game development or web development. C++ or Java can be used for creating servers, and so on.
