If you are thinking about jumping into an AI course online, you don’t need to know everything upfront but having some basics really helps. H2K Infosys does a pretty good job easing beginners into all this without making it overwhelming, which is honestly what most people need at the start. Python is the big one, almost everything in AI leans on it, and honestly, it’s not too hard to pick up. A bit of exposure to R can come in handy if you’re dealing with stats-heavy stuff, though it’s not always essential. Some people also find it useful to have seen languages like Java or C++ before, especially to understand how things work under the hood but I wouldn’t stress too much about mastering them. What matters more is getting comfortable with general programming ideas loops, data structures, that kind of thing because those concepts show up everywhere.
