Can someone please answer some of my questions. First, can someone learn python after knowing only html & css and then make a job out of if? How important is Java compared to python? What languages do you feel would a person prefer to know for both front end and back end development?
I had a lot of questions and will appreciate any feedback in partial and/or full.

they're mutually exclusive. you can learn one without the either just fine.


javascript is all the rage for front end. you can also use javascript for the backend via nodejs if you wish, but you don't have to.
