   Go to https://www.edx.org/course/introduction-computer-science-mitx-6-00-1x-11 It's a free MIT Python course that uses 3.5 It's an amazing class. It's 50$ if you want the certificate for your resume. Cheers.

   I agree with ASIC_SP. I went through the book and it was great. It doesn't teach you anything about Object-Oriented Programming but it is a nice start. MIT has a free course that is consistently praised, https://www.edx.org/course/introduction-computer-science-mitx-6-00-1x-8. I took this course…

   I'm sorry if I sound harsh, but there are a lot of people like you coming to this forum with similar stories of wanting to change careers and looking for a low barrier to entry position in the industry. Programming is not the right industry for that. If someone does manage to get a job in only a…

    See the FAQ; almost all online C++ resources are of rather poor quality. Try the Udacity course on Python: it's mostly video, so you won't have as much trouble with that, and it's well-paced.
