I see you have yet to start python course. I highly suggest to go through the python course here at Sololearn.

HTML and CSS are easier compared to python.

HTML is like a declarative language. Here you don't worry about the inner details. For example, if you want a table then you just write <table> tag and table is automatically drawn for you by browser.

But Python is an imperative language where you have to worry about the inner details. Here you have to work with programming constructs like variables, loops, conditional blocks.
If you want to draw a table through python you ll have to render the table lines yourself.

Python will be fun just try it out. Even if you don't learn python and continue learning HTML and CSS then your natural progression would be Javascript.
Javascript(nodejs) can also help you do what python does.

So no worries 👍, I say just jump into the course and try for yourself.
