EDIT : I am 30 years old. I am changing my career. I want to learn programming. But I have not programmed ever before. How can I start my career in tech world?
There's a lot of courses in Massive Open Online Courses (MOOC) [1] site which you can dip your hands first to try to learn some technical stuff.
You can also go to the Free Code Camp[2] where you can get some real-world training in software development. They have a lot of stories[3] as well showcasing people who were self-taught and now have stable careers in the technology field.
Career opportunities would come as soon as you have showcased that you are capable of learning and solving technical stuff. But you got to start first by learning the ropes of software development.
PS: Lots of assumptions as you haven't provided more details to provide specific advice.
What industry are you currently working in? If you have accrued good domain knowledge, then you might have an edge.
Learn programming on the side (self learning, bootcamps, Coursera etc etc) and (Python probably) and aim for software jobs in the that industry based on your domain knowledge. Someone might be willing to offer a junior programmer role, allowing you to learn on the job? Or even your current employer might let you transition to their internal IT etc?
Please try to leverage what you have, instead of starting from zero. Hope this helps. Best.
One thing you should learn is how to answer these types of questions on your own -- you'll be doing it a lot once you begin your career (searching "how to code" would yield a lot of useful results).
