The part of this that is Set up Environment Variables and PATH can be handled by Python's virtualenvs. You create one starting from a possibly local Python layout, or from a system one, and the virtualenv handles all the "fiddling" so while that env is active, just "python" and "pip" work for that environment. A nice way to manage this is through a project called pyenv. There is now a Windows port of this so it can work there as well (I've never used it on WIndows, personally). So while there may not currently be a zip/tar archive you can unpack and go, I can get started quite easily on a new version. Let's say I decidded I needed to test something on Python 3.7 but my main Python is already 3.10: pyenv install -l | grep "3\.7" ... list of available versions that contain 3.7 pyenv install 3.7.12 # sets up 3.7.12 in pyenv's local versions tree pyenv virtualenv 3.7.12 venv-3712 # create virtualenv using 3.7.12 as base pyenv activate venv-3712 and now I'm running inside a virtualenv using 3.7.12, which I can now provision for the work I want to do... -- https://mail.python.org/mailman/listinfo/python-list
Re: About Python Compressed Archive or Binaries
Thanks I really appreciate that, its time consuming task and take lots of hard work for sure, I was thinking it's technical issue for python that there isn't binary format for it, so I'm happy to hear that we will have that option in the future 🙏🏻🚀 From: Python-list on behalf of Christian Heimes Sent: Tuesday, January 18, 2022, 18:29 To: python-list@python.org Subject: Re: About Python Compressed Archive or Binaries On 17/01/2022 18.49, Kirill Ratkin wrote: > It would be nice to have just zip file with python interpreter (not > executable installer), unpack it anywhere, add path to this 'anywhere' > to PATH, and use it. > > Java/DotNet/Go have this option.

It is most likely the same forum... The Python mailing list (which does get spam filtered, unlike the Usenet newsgroup, so doesn't see as much junk injected via Google) is gatewayed with Usenet comp.lang.python. comp.lang.python is what Google gateways for its Python group. Anything posted on the Google Python group is seen by comp.lang.python, and from there gets seen by the Python mailing list (and things go the other way also). The only difference is message management -- email vs news reader vs whatever Google's interface of the week inflicts, and how much spam comes through. For me, mailing lists take too much management to set up filters to file mailing list traffic to a special mail box (and then if I need other filters, to ensure they apply before or after the mail box filing) whereas a decent news reader automatically files messages by their group. And you really need to find a client that follows (or properly use the one you have) email/netnews /threading/ and attribution conventions. Avi Gross's post was on a different path (there was a three-way split from your earlier post).

I'm in a fey mood today... The OP (and the rest of you reading) will
likely just skip this message... It's a rambling free-association harangue
on a possible RDBM schema -- which makes a few assumptions (described
following) and looks wildly different from the OP's vague data...
Inferred from various posts is that this
* NOT a library (which may have at most 5 copies of
popular
books)
* NOT a book store (which would not have
check-out/check-in
dates)
The best use case I can see is for something like a high school in
which textbooks are issued to students at the start of the course, and
collected at the end. For a small high school, say 600 students, there
might be 150 taking, say 3rd year Trigonometry, split among 6 session of 25
students each day. This justifies not tracking every copy of a book by full
title, et al.
I'm going to take that as the overall system CONOPS.
Needed data: book title, book author(s), ISBN and/or other call number
(some texts may be old enough to predate ISBN), # copies, # available,
dates for check-out and return, student name. Probably more as I go down...
Schema format notation:
relation(attribute list)
special constraints description
where
*attribute* is a non-null, unique index, primary key (preferably
autonumber)
_attribute_ is a non-null, duplicates allowed index, foreign key (in
the form relation-attribute)
/attribute/ is an optional/alternate indexed attribute
Publisher(*ID*, name)
Book(*ID*, ISBN, alt-call, title, _Publisher-ID_, copyright-date)
constraint(ISBN not null OR alt-call not null)
Author(*ID*, /last-name/, first-name)
constraint(last-name not null)
Book-Author(*ID*, _Book-ID_, _Author-ID_)
{this links authors to books, and allows for books to have more than
one author}
Copy(*ID*, _Book-ID_, copy-number, status, condition)
constraint(status in "A", "O", "R", status not null, default "A")
constraint(copy-number not null, [Book-ID copy-number] is unique)
{A = available, O = checked out, R = reserved but not yet
checked
out}
{condition contains notes on known damage, etc. for this copy}
Student(*ID*, /last-name/, first-name)
constraint(last-name not null)
{I expect this to expand with student ID number, home address,
etc.)
CheckOut(*ID*, _Copy-ID_, _Student-ID_, reservation-date, checkout-date,
due-date, active)
constraint([Copy-ID Student-ID] is unique)
constraint(active not null boolean default true)
{can automate cancelling reservations after n-days, and can
also be
used to produce a list of past-due}
{active is used to allow for history of check outs, set to false
when book is returned (and hence made Available again)
SEVEN relations (aka "tables") in an RDBM. While each book /title/
appears only once, it does take a small record to identify each copy of the
book and track availability of the copy. Reserving a book requires
transaction to select the first copy with status = "A" for that title,
update status to "R", insert a checkout record with the currently selected
student and current date for reservation date. When actually given the
book, a transaction to find the active checkout record for the student, for
that title is done, the checkout and due dates are set, the copy record is
updated for status = "O". When returned, a transaction is done to locate
the checkout record, update active to false, update Copy record to set
status to "A", and optionally update the condition field to indicate
damages inflicted by the student while it was checked out. If a reserve
operation fails (another session snagged the same copy record and updated
it) one just repeats the transaction trying for the next available copy
record -- only if there are no copies with status "A" do you have to abort
and tell the student they can't have the book.

Re: What to write or search on github to get the code for what is written below:
I do not manage any python lists or have any say in how they run so I have no idea why I am being asked by name below, as Dennis pointed out. So I won't reply on whatever I am being asked, but want to point out that many forums may be asked questions and some people on the forum will not respond or will not accept a user that bombards with too many questions or requests for more detailed answers and especially when not given enough but appropriate information. Not everything in life is free. Python as a free language is but the expertise in ways to solve specific problems using Python, let alone EXCEL, that you want, often is not. Simple requests like how to read in data from a format like .CSV or a tab in .XLSX files can be easily answered, of course. But correcting what sounds like a horrible data storage without a redesign is often not of much interest to others. I think this group has already spent way too much time on whatever this issue is and provided lots of useful advice which apparently does not get taken. So don't pull me in again.
