I want start with python but I don't know what operating system and tools to use. I have a 6 RAM icore3 180 GB hard disk Notebook laptop running Linux mint. I plan to save up to Buy a PC in the future but for I have to make due my old laptop
I am also wondering how does the programming market look like in terms of operating system. Does it matter which operating system you use? In terms of programming institutions (universities bootcamps, etc..), do each institutions have its own preference or does it let its student choose?
You're on Linux Mint already, which is great. As others have said, Linux drives the world. Pretty much anything you write for a server will be running on Linux.
There's a high likelihood that universities will either have a programming environment from before 2010 or before 2020. They are often slow to change. Bootcamps mostly use the tools that are most hip.
If you want to start with Python, I recommend and integrated development environment (IDE) like PyCharm. It handles a great deal for you and allows you to learn the low level stuff and python tooling at your own pace. Stuff like virtual environments, debugging with breakpoints, documentation,
If you're interested in anything surrounding data science JupyterNotebook is great as it allows you to see the output of your code as you progress. That output can also be visual (graphs, images, variable values, etc.)
