Do you know any good training courses in software development?

I've noticed that many people who want to change careers or learn how to program attend boot camps.
What are boot camps?
A Bootcamp is a kind of accelerated course, usually, they last two or three months (8 hours a day, 5 days a week), and you learn to program with the help of teachers.
Let's take Ruby boot camp as an example.
They teach you how to program in Ruby and how to use databases.
You do your first real project as a team, and later, because of that, you get really good at the basics and can get your first job.
I took a very good programming course at https://www.nopio.com/blog/become-a-software-developer/, they give you a lot of useful knowledge that you can use 100%.
There are not some courses in 2-3 days, these are professional courses where you can grow as a specialist if you have a strong desire and persistence.

I once took a month course and it didn't really work out, just because I now understand that it takes more than a month to become a programmer, but in addition to that, it takes a lot of practice.
