How to install Beautiful Soup 4 without *any* assumptions
With a little help from the kind user Tenacious B, I have solved my problem, I think. In the command prompt, I needed to type 
cd C:\Users\%userprofilenamegoeshere%\AppData\Local\Programs\Python\Python38-32\scripts 
No source that I found in my initial search included that last bit: \scripts. From here, the common suggestion of pip install beautifulsoup4 seems to have worked.
I need to install Beautiful Soup 4, but every tutorial or list of instructions seems to assume I know more than I do. I am here after a number of unsuccessful attempts and at this point I am afraid of damaging something internally.
Apparently I need something called pip. I have Python 3.8, so everyone says I should have pip. Great. I have found no less than 14 different ways to check if I actually have pip and am using it. They all say to type something. One of them said to type pip --version. We are already assuming too much. Where do I type it? IDLE? The Cmd prompt? The Python shell? What folder do I need to be in? Etc Etc. I need someone to assume I am a complete beginner.
Then, how do I use it to install bs4? Again, I am supposed to type things, but no one says where. One person said to go to the folder where python is installed in the command line. So, I did, and surprise surprise, pip is not "valid syntax". How can I proceed with this?
