I now have uninstalled everything, again. The last uninstall was the anaconda way.
Just as info you can have both Anaconda(my tutorial) and Python eg python.org Python 3.7 installed at same time the do not interfere.
I just answer a question about here.

No need to pay for answer(private) use the forum it's free as it always will be.
Try link i posted,have problems make a new Thread.

Quote:IDLE is still available, and still not very good. There are many IDE's available that are free and very good. VSCode and PyCharm are two of the better ones. If interested in VSCode, see https://code.visualstudio.com/
and : https://visualstudiomagazine.com/article...ython.aspx
It will run on any platform, and is very good
I used PyCharm for a long time and really liked it. I had some trouble using with virtual environment, but no problem with VS Code. Now myself, snippsat and others use VSCode.
See also snippsat's writeup here: https://python-forum.io/Thread-Need-some...telliSense
So I will get back to you when I have read everything, but after a clean up on the PC, I was left with various versions of Python, will post those version numbers soon, to use same or file away.
But hope this will be my own "get started from scratch" thread, hope others to may benefit.
Any further suggestions most welcomed
Thanks
Current versions of Python install for win 7 are
2 of
python-3.6.5
1 of
IDLE Lif 1.1-Py26
1 of
beautifulsoup4-4.6.0.tar
but seems corrupted, opens in word.doc only.
1 folder named:
dist
inside that folder a file named :
beautifulsoup4-4.6.0
and finally a pdf file named
conda-cheatsheet
They all did my head in !
Ok, have downloaded and installed the latest version
python-3.7.0 ( win 7 pro )
IDLE is on task bar, it will open a current .py file.
But the .py files on their menu bar don't associate Open With IDLE,
it's not there.
Secondly, I think it may not be installed right, directory to install was changed to C:\
Maybe I should have created a folder and installed inside that folder ?
C:\folder_name\ Python installed here ?

You can choose folder like

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
>>> bs4.__version__
'4.6.0'

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.

I been reading and practicing some stuff, but starting to see a bigger picture.
On the question of Librarys, I started to look into a few of them, there seems to be thousands complimented by their authors or script writers. So basically the way I'm starting to see it, instead of writing the same ol same ol scripts, just call a script from the library, right ?
If that is the case, looking at my current Excel VBA project that runs OK, eventually I can create my own set of .py Library scripts, and use my own folder to call those scripts ?
The goal is to move away entirely from Excel, even create my own GUI ?
Thanks

Yes there are two main
Standard Library(comes with Python) |
PyPi(3-party library).
Standard Library:
>>> import math
>>>
>>> # 8^2 in math
>>> math.pow(8, 2)
64.0
PyPi(here need to us
pip to install)
Example
Requests
pip install requests
>>> import requests
>>>
>>> r = requests.get('https://www.python.org/')
>>> r.status_code
200
>>> r.encoding
'utf-8'
>>> r.headers['date']

Yes can create own small libraries and module/packages,there are som stuff to be learn if want to share with world like on PyPi.
There are many tools for Excel in Python like
Pandas,
openpyxl,
pyexcel.
Pandas with
Jupyter notebook is one of the strongest as you get a look similar to excel(can replace Excel all together).

OK, I un-installed everything, again.
Made new folder as suggested "Python37" and re-installed.
Instructions are a bit different for the 3.7 version only slightly, but ran the first script and copy/paste what is on the CMD screen.
Seems a lot cleaner to make that own folder.
I don't know what this part means though:
Quote:The script chardetect.exe is installed in 'c:\python37\Scripts' which is not o
n PATH.

ing, use --no-warn-script-location.
If you open a terminal, and run the following, what output do you get?
python -c "import requests; print(requests)"
If it's an error, then that might mean you should fix your PATH. If it's not, then you can ignore the PATH warning. That message is letting you know that the Scripts folder isn't on your PATH, and the PATH is how Windows knows where to look for files.
Then your PATH is fine, and you can ignore the warning :)
