I learnt from a book but that was a long time ago there might be some online courses too.

Personally I think there is nothing wrong with picking up programming from a book. When I went to university 25 years ago and did computer engineering we spent more time being taught software engineering concepts. Example operating systems, compilers, computer graphics ray tracing, artificial intelligence (expert systems, neural networks, language recognition, searching), software development processes. Programming was just a tool we never had a course called programming we were just were taught the concepts and had to develop a project based based on the concepts example a ray tracing application, an expert system etc...

We were expected to pick up the languages ourselves. If you are not able to pick up a language from a book maybe programming might not be right for you due to lack of interest or you might have have also picked up the wrong book.

If you have not programmed before it’s better to pick up a book with some exercises at the end of each chapter with sample answer programs. If you don’t have exercises to practise you would most probably finish the book and still be totally confused.
