What languages should I learn for building a website?

Question

I have a solid understanding of Pyhon and Java from courses I took this year at the university I go to. I understand that HTML and CSS are the basics required, with Java script being used for functionality and SQL for Data management. What else is required, or what should I learn more of?

Answer 1

HTML, CSS and JavaScript is used to develop the front-end of the website, i.e. the part which a user looks at.
SQL is used to manage a database present at the server. however, to interact with that database, you need a server side language, like PHP.
this server side language and SQL constitute the back-end of the website, which the user don't see.

Answer 2

You should learn everything there is to learn. (I know that sound stupid but it's true). You should start with the basic and then work your way up to more complex things.
