I'm looking to pick up Python, but I'm not sure if I should dive in and learn everything from the ground up again, considering I have some experience with JavaScript. Should I start with the basics like data types and functions, or can I just focus on the syntax differences and jump right into projects? If the latter is a better approach, how much time should I expect to dedicate to learning Python? Are there any resources that can help bridge the gap between JavaScript and Python?

Consider why you want to learn Python over other languages. Instead of just picking randomly, it might be better to focus on a specific field, like AI or data science, and learn relevant languages and tools for that area.
While Python and JavaScript are different, if you know JS, you can skip to learning Python's specific syntax and features. Spend a couple of weeks practicing and coding on small projects. Tools like Exercism or JetBrains Academy can help you focus on areas where Python differs from JavaScript.
Check out guides like "Python for JS developers." They usually highlight the key differences, which can be really helpful. You might want to skim through a quick start guide that gets right to the point without rehashing the most basic concepts like loops.
I used the documentation to pick up Python basics, and these days I utilize Claude. I write out how I’d solve problems in JavaScript and let Claude convert those into Python with explanations.
Since you’re already familiar with JavaScript, you can bypass the beginner textbooks. Start with *Learn Python in Y Minutes*, and explore the official Python documentation. Also, try playing around in JupyterLite for hands-on practice.
