Loaded question. For gaming/programming should I go with a laptop or pc? [I Build Computers]

But I have more questions. I have very limited knowledge of the internal components and what types are compatible with each other and what each type has to offer in terms of performance.

Let me put it to you this way, I want something affordable that isn't going to blow a hole into my checking account and I will spend extra money if I have to. I'm not looking for intense gaming, maybe steam games or league of legends but I also want to get back into programming such as C#, python, javascript etc. This computers intended use is to start retraining and reteaching myself since I don't have time or money to go back to college.

So what I'm asking for is helpful advice. Good places to design my own PC if the laptop option isn't viable which is what a lot of people are leading me to believe. Websites so I can educate myself on these specs such as CPU, graphics processor, etc. And in your opinion some of the best overall specs and brands to go with.

Again loaded question but I appreciate any advice on this. Basically I have a craving for knowledge once again. Ive spent too long spending my days off lounging on the couch and doing nothing. I want to re-educate myself especially in foreign languages, computer programming and database systems, discrete math, all the good stuff.
