How to Install Python on your Laptop
There are many different ways. Important for this course is that you have installed the correct version of Python. Anything after version 3.7 should be enough. Any version starting with 2 will be to old. Some operating systems still come with such old versions, so it's worth checking.
For your own laptop or workstation, possibly the easiest way to install Python is to use Anaconda, as that is available on Linux, WIndows and MacOS. However, plain python should work as well.
Note that Anaconda is more than just Python, it has mechanisms to install more than just Python and its packages. Precisely for that reason, Anaconda is generally not recommended for shared resources such as the supercomputers that SciNet,where there are other, better ways to use Python and its packages on those system.
It is also quite likely that the Anaconda license does not allow you to use it for research conducted at the University. For your own computer, however, anaconda is an easy way to get a Python installation.
