When learning your foundational language (like Python), focus on understanding concepts instead of memorizing syntax.
For example: print() outputs to the console. Don't memorize the function — remember the concept: "Python has a way to print to the console." When you forget the name, just search "how to print to console in Python."
This method doesn't stop at your first language. When you pick up Java later, it gets easier — you already know any language can print to a console. So you just search "how to print to console in Java." After that, you dive into the internals when you need them.
Syntax, implementations, and internals change between languages. The core ideas stay the same: loops, printing, conditionals.
