I don't remember how I installed python. I'm learning to use Jupyter now and the official website recommends to install python using conda, not pip.

1) Why is installing python and Jupyter with pip not advisable? I understand the difference between pip and conda, but can someone please explain to me why Jupyter recommends to use conda to install it? Is there a way for me to check how I installed python? Should i reinstall it with conda if I used pip?

2) I'm trying to understand the whole conda is a package installer but also manages venv. typed "list" into the anaconda prompt and it gave me a list that I have some questions about.

(base) C:\Users\ellie>

2.1) does this show me a list of all my packages or just the packages i installed with conda?

2.2) according to conda.io, "Conda channels are the locations where packages are stored". What is a "pypi" location? How is that a location? Also, it says at the top that everything is stored at C:\Users\ellie\anaconda3:. So how is a channel different from the C:\Users\ellie\anaconda3: lcoation?

3) Is there a downside to moving the default jupyter notebook location to somewhere other than the C drive? / Is anyone else's jupyter home directory (http://localhost:8888/tree) filled with garbage like a desktop folder and some shit you installed 80 years ago? None of the tutorial people have their entire lives in their tree directory, so this makes me wonder where I went wrong. I'm sorry that this is the dumbest question ever. Is there a reason Jupyter made a folder with a bunch of garbage in it my home directory? Is there a downside to moving my home directory to the D drive?

Installing Anaconda encompasses python and the conda package manager. Anaconda is a tool, or framework, containing very many useful tools and programs to work with (big) data.

I believe the reason Jupyter wants you to use conda, is to make sure the dependencies are already installed, and the fact that it is mainly developed for the Anaconda environment.

Speaking of venv, the reason it is installed is that Anaconda also functions as a environment manager, letting you choose your installed packages and versions. For example, you could create an environment which uses python2, and install only python2 libraries in it, without changing the root environment.

If you used pip to install python, i recommend just installing Anaconda as a whole. Jupyter without Anaconda is also feasible, but does not nearly have the same amount of support and frameworks, and fiddling with the jupyter-libs is not something that pays off (trust me, I tried myself).

The bottom line is that pip gives you more freedom in what you want to install, but conda is easier to use and recommended for data-driven programming. They can co-exist without a problem (except maybe some problems with your path, which should be really easy to fix, judging by the amount of questions about this topic on StackOverflow.).

I personally use Jupyter strictly with Anaconda, because it lets me switch between projects on-the-fly without worrying about having the right dependencies available, and it lets me use JupyterHub, which is a big plus in my book. Also, it spares me the hassle of fiddling with the jupyter versions, which can be a real pain.

2.1)

These are all packages that either were shipped with conda, or you yourself installed with conda. However, if you want to be sure, you can check your pip packages by running pip list. Your pip packages should be stored somewhere else on your machine, so your python installs do not get in each other's way. Thankfully, this is the default.

Channels are NOT a location on your drive, they are locations on the conda cloud. If conda looks for a package to install, it iterates through a hierarchy of channels, until it finds your requested package or finds nothing on any channel. You can to some extent control this hierarchy, but as a beginner it is not important. The channels that are important, however, are those that are given by your operating system; if you use Windows, only packages are found that are explicitly availiable for the Windows operating systems. These packages, in turn, are organized in a channel, mostly named after your os. These packages are then installed on your drive in a folder with the same name as the channel, so conda can keep track of the different packages you have installed for different os's.

It is possible (and recommended) that you start your Jupyter Notebook in the respective folder, either by using jupyter notebook --notebook-dir '<your folder>' or by changing the jupyter start folder.

On a sidenote, most of the questions you asked here are already answered on this site, and with a little digging you could have answered most of these questions beforehand.

Nevertheless, i am not a Anaconda pro myself, and channels are a concept that somebody else might elaborate on some more.
