Where are professional courses in programming languages ​​python, java, etc. held?

Question

IT education

All the best!
Friends, I ask for advice.
I decided to change my occupation and learn to be a java programmer or a python specialist and the like.
For the main focus, I consider java (I don’t know how relevant such specialists are in the labor market).
In general, I am looking for professional and high-quality courses (preferably with employment) from scratch.
I plan to move in the direction of the web industry.
Can you advise something?

Answer 1

Professional courses in the programming languages ​​python, java, and many others are held in many books that can be bought at the Amazon store.

Answer 2

mUchenik , You
can basically wipe yourself with a certificate. I don't know any python certificates that would be listed in the world.
A technical interview will ask a couple of questions and find out what you actually know about.
There are no professional python courses with employment. Because there is a catastrophic shortage of professionals on the market, and a professional can get a job without certificates very quickly.
Courses "with employment" is a common infobusiness, when courses are given for beginners, but among 100 students. A few of these students (who have actually been writing scripts for themselves for several years, they just get sick of going to an interview without a paper and decided to go to courses in order to "officially" register) can successfully get a job on the recommendation. They will definitely be told about them - how the graduates of the courses got a great job in Google / Yandex / etc.
I do not argue that many such courses can provide good material and, with sufficient duration, give generally good basics. But if a person is able to learn this material in the courses, he is DEFINITELY able to master it on his own - the benefit of the material on the Internet is now heaps.
Finding advanced courses for mid players, and even more so for seniors, is impossible due to their absolute lack of demand. At most, these will be various reports, hackathons, conferences where they simply share their experience about different tools in an overview. But these are not courses with training and practice.
