getting started, again

[snippsat]

C:\folder_name\ Python installed here ?

You can choose folder like C:\python37 in follow Python 3.6/3.7 and pip installation under Windows

beautifulsoup4-4.6.0.tar
but seems corrupted, opens in word.doc only.

You use pip to install all Python modules/libraries.
That's why is important that you follow link over,and do test that pip work from anywhere in cmd.
cmd:

C:\>python -V
Python 3.7.0

C:\>pip -V
pip 10.0.1 from c:\python37\lib\site-packages\pip (python 3.7)

# Install BeautifulSoup 
C:\>pip install beautifulsoup4
Requirement already satisfied: beautifulsoup4 in c:\python37\lib\site-packages (4.6.0)

# Test that it work
C:\>python
Python 3.7.0 (v3.7.0:1bf9cc5093, Jun 27 2018, 04:06:47) [MSC v.1914 32 bit (Intel)] on win32
Type "help", "copyright", "credits" or "license" for more information.
>>> import bs4

IDLE Lif 1.1-Py26

IDLE is not good at all.

I will suggest maybe the easiest editors/IDE just to get started like PyScripter or Thonny.
Then later you should look at editors like VS Code(Free), PyCharm(free communty edtion).
My quick review a while back of VS Code.

Demo PyScripter you can just write code and Push run button,not even need to save.
Then in bottom you hav much better IDLE,where output will be and further testing can be done.
