Download from where? (There are a number of distributions available,
including ones in the M$ "app" store, Visual Studio, etc.)

"Add Python..." is a step when RUNNING the installer. It should not
appear when DOWNLOADING the installer.

The general sequence is:

Download the installer file for the distribution.

RUN the installer program to install Python (and any other stuff
the distribution includes)

Hide the installer program/icons -- since they do NOT run Python
itself. Pure Python is run from a command line/shell interface; it is NOT a
graphical IDE.

Hello and welcome,

Sadly I don't know about Eset internet security, or why you do not get the 
choice of letting the installer do that, but you could try to add Python 
manually to your PATH like it is described in 
https://www.geeksforgeeks.org/how-to-add-python-to-windows-path/ .

But maybe some more windows savvy people than me might chime in to offer better 
advice ;-) .

Cheers

I guess that you're using Windows 7 since Windows 10+ includes the
Universal C Runtime (ucrt) as a required system component, for which
"api-ms-win-crt-runtime-l1-1-0-dll" is a virtual API set (mapped to
ucrtbase.dll), which can never be missing, and since Windows 8.1 is
relatively uncommon (2-3% of installations).

Python 3.10 requires Windows 8.1 and above. If you're using Windows 7,
you should be able to install and use Python 3.8.10:

https://www.python.org/ftp/python/3.8.10/python-3.8.10-amd64.exe

If you need to install ucrt, here's the link for the update that was
released in 2016:

Insufficient information (you've given the equivalent of "my arm hurts"
without stating which arm, where it hurts, and the nature of the pain; a
big difference between "it was caught in a door jamb" and "a chainsaw cut
it off").

Where are you downloading from (the URL might be of use), which version
(if there are more than one version at that URL). WHAT OS! For Linux it is
often easiest to just use the distribution package manager to
install/upgrade Python.

What happens when you run the downloaded file? How are you trying to
run Python?

What happens if you open up a command shell and enter just Python (or,
for safety python3, since you shouldn't even be looking at python 2.x but
some Linux distributions still use 2.x for there own uses)

Python is not a development environment. It is a compiler/interpreter
for files containing Python source code, normally run from a command shell.
Many installations do include a Tkinter-based program called IDLE which can
be run if one really needs an IDE -- though there are many third-party IDEs
for Python which may be better.

I assume you typed "python".

And I assume that it is because you have python 2.7.17 installed and its on
your PATH.

To run python 3.9.1 do this in cmd.exe

py -3.9

It is also likely that just typing "py" will run python 3.9.1.
Typing "py -2" will run python 2.

Run this to find all the versions of python that you have available:

py -0

Re: Downloading Python

It's quite possible you have a version mismatch. Try installing python 3.8
first.

BtW, before the would you like to check what version python command reports.

Sorry for top post.  I am sending from my phone and bottom post pretty
confusing here.

I don't know what "[a]fter downloading Python 3.8.5 IDLE" means to the
OP. For a successful installation of Python 3.8 using an "executable"
or "web-based" installer from python.org [1], the file "python38.dll"
will be installed in the same directory as python.exe and will thus
always be found.

The Python Launcher exists for this purpose.  Otherwise, as Abhiram
notes, you have to add to PATH, which on Windows is a bit of an
irritant, because that path entry will change as the Python version
changes (e.g. when you change from 3.8 to 3.9 you'll have a different
default path location). Try locating Python by using the command

py

in a command shell (or in PowerShell).

It's most likely because you haven't added Python to your environment PATH
variable.

The easiest path forward is to uninstall it from Applications and then when
you reinstall, tick the option on the bottom of the first splash screen of
the installer. It will add Python to your PATH variable automatically and
you should be able to access it from CMD after that.

Forgot to mention this,
Anaconda comes prepackaged with numpy, pandas, scripy and other data

Since you need numpy and as a grad student too, I'll strongly suggest you

Trouble Downloading Python and Numpy

[Contreras, Brian J]

Good Morning,

I am a research student at the Georgia Institute of Technology. I have made 
multiple attempts to download different versions of Python with Numpy on my 
Microsoft Surface Book with no success.

I ensured that I have space for the program and the latest windows 10 update, I 
still am unable to open any python files or write code within the program. I 
was told by a colleague that I may need a python path environmental variable, 
but I have not found asite that provides this.

If I could get some support with the download I would greatly appreciate it.

Warm Regards,

Brian Contreras

Welcome to Python!

Announcement mailing lists, like this one, are typically used by python
package maintainers to publicize the availability of new versions of their
software. You could consider it much like a Tannoy system, it is loud,
everyone can hear it, but it is not used very often.

If you are a total beginner, then I would recommend starting with; Python
For Beginners <https://www.python.org/about/gettingstarted/>, really there
is no substitute for ploughing through the introductory documentation.

This is part of the release process.  3.4.3 was fine last I checked, so perhaps 
some wonderful automated process broke it for me.  3.5, I think I simply didn't 
upload the docs properly.

Anyway, this is my responsibility as RM for 3.4 and 3.5, so in the future if I

much MUCH smaller set of common code, with most attacks being aimed at

Sure, but there's a significant difference here.

If I were to run pip install foo, I'm explicitly choosing to trust that 
code. If I don't trust it, I simply don't run pip install. Merely going 
to the PyPI website for package foo doesn't run foo, nor does viewing 
the code, or even running hg update (or git) on the repository. By 
default, foo doesn't run unless I explicitly run it. pip is *fail safe* 
-- if it fails, or if I don't run it, nothing gets executed.

In contrast, if I go to foo.com, the default is everything will run. I 
have *no idea* what's going to happen until I get there. The default is 
run anything, unless explicitly turned off instead of don't run, 
unless explicitly turned on. Even if I run NoScript in my browser, or 
turn off Javascript in my browser, I'm hoping that there isn't some 
executable protocol that NoScript doesn't block, or only partially blocks 
(What do you mean web fonts contain executable code?), or maybe I 
turned Javascript back on so some other site works and forgot to turn it 
off again. Our browsers are fail unsafe -- if they fail, they can run 
untrusted code.

You can't even say well if you don't trust foo.com, don't go there 
because while foo.com itself might be trusted, they're probably selling 
advertising, and the advert itself is executable and could come from 
anyone, anywhere.

Imagine that every time you walked into a shop, the shop could instantly, 
irreversibly and silently deduct whatever amount of money from your 
credit card it liked, unless you remembered to put your credit card 
inside a metal wallet before entering the store. But most stores won't 
let you in if you do, or at least the shopping experience is painful. So 
we just hope that the store won't take advantage of that ability and rob 
us blind. That's not too far from the Internet security model.

Re: Can I trust downloading Python?

[Wolfgang Keller]

 Every time you go on the Internet, you download other people's code
 and execute it. Javascript, Flash, HTML5, PDF are all either
 executable, or they include executable components.

That's why I deactivate all of these by default. And why I *hate*
so-called web designers who *require* activation of such fancy flashy
nonsense gadgets.

PDF files are an exception since PDF was originally designed as a
safe subset of Postscript (postscript viruses had been demonstrated).
Now Adobe has jeopardized this by allowing embedding of Javascript in
PDF files (but that as well is deactivated by default for me).

Sincerely,

Wolfgang

 that level, you become paranoid to a point that's inappropriate to all

 that sort of paranoia if you're running a nuclear power station, or an
 automated weapon system capable of firing missiles that destroy the

 there's no point panicking.
 
 Also: That hack works beautifully when there's precisely one C compiler.
 In today's world, there are many (well known ones like gcc, clang, MS
 Visual Studio (whatever the compiler from that is called), and a bunch
 of lesser-known ones as well), and it's pretty easy to just grab a
 different compiler and build. The chances that your code will be falsely
 compiled by TWO compilers would have to be infinitesimal, and you
 needn't stop at two. 

That logic is dubious. Compilers aren't compromised by chance, and we 
don't know the a priori probability of any specific compiler being 
compromised. That depends on the attacker, surely? We know, for example, 
that the NSA has compromised multiple brands of router, smart phone and 
similar. If they, or some other similar organisation with equivalent 
capabilities, were going to attack compilers in the same manner, they 
surely wouldn't stop at one.

Would people notice? How often do people compare the machine code output 
of two different compilers, looking for back-doors in the generated code? 
Would you know where to look? If you found some differences, wouldn't you 
likely just chalk it up to different compilers producing different code? 

I think the best argument against this suggestion is that it would be an 
order of magnitude harder to compromise open source compilers, as you 
discuss below, and therefore gcc is *probably* (but not certainly) safe. 
But closed source? If Microsoft inserted a backdoor into Windows 8 on 
behalf of the NSA, as seems to be the case, then surely they'd also do 
the same to Visual Studio if asked.

Organisations like the NSA don't operate under the rule if there is one 
single uncompromised machine on the planet, we've lost. It's a numbers 
game. If (hypothetically speaking) they had inserted backdoors into 
Visual Studio, gcc and clang, but not Larry's Cool C Compiler, I don't 
think they're going to lose sleep over that.


 Since many people build (to take one example) gcc
 from source, using an old version of gcc, the hack would have to be
 propagated to all current gcc builds in some way - you can't simply
 build once and install the binary as the official C compiler, not in
 today's distributed society. (If you're truly paranoid, you might
 believe that gcc has had the hack in it since its inception. But some
 people build gcc using other compilers, too.)

Yep, I agree -- although probably no individual has inspected the entire 
tool chain involved in building gcc, enough people have inspected each 
individual component that we can be reasonably confident that it is okay.


 If you can't trust any code you didn't write yourself, 

You trust yourself? You sheeple! The truly cautious man doesn't even 
trust himself. You might be an unconscious sleeper agent. Haven't you 
watched The Running Man?

nearly impossible to detect and a very elegant solution to a tough problem.

Indeed it is really paranoid territory, but now doesn't seem quite as

Agreed.  Most of the damage done by the NSA is in the realm of social
engineering more than technical.  IE they compromise companies more than
the algorithms themselves.  The end points always are the weak things.

Hello, the 1990s called and want their stereotypes back.

Malware in 2013 is not about loser nerds erasing your hard drive for the 
lulz. It's a multi-million dollar a year business, mostly driven by 
spammers, but with small yet profitable niche markets for industrial 
espionage and blackmail (we've encrypted your files -- pay us $100 and 
we'll send you the key). Plus so-called law enforcement[1] uses it to 
break into people's computers, for keylogging, etc., and you better 
believe they have cracks targeted at Linux. Of course, Linux is a much 
harder target than the average unpatched Windows box, and there are 
probably easier ways to get access to your files if they really need to.

But really, we've learned *nothing* from the viruses of the 1990s.

The people driving malware these days are not script-kiddies, but 
professionals, up to and including some of the smartest and most highly 
funded professionals in the world. Stuxnet anyone?

Any add-on package which provides pre-compiled binaries will provide

 When it comes to NSA spying, before Edward Snowden, there were these

That is quite true, and yet not truly helpful here :) It's like
pointing out that we could be being fed false information, and then
suggesting that The Matrix is technically possible. Once you start
distrusting to that level, you become paranoid to a point that's
inappropriate to all but the most critical situations. I'd accept and
maybe even recommend that sort of paranoia if you're running a nuclear
power station, or an automated weapon system capable of firing
missiles that destroy the planet, or a bank that holds everyone's
money. For the average Joe, there's no point panicking.

Also: That hack works beautifully when there's precisely one C
compiler. In today's world, there are many (well known ones like gcc,
clang, MS Visual Studio (whatever the compiler from that is called),
and a bunch of lesser-known ones as well), and it's pretty easy to
just grab a different compiler and build. The chances that your code
will be falsely compiled by TWO compilers would have to be
infinitesimal, and you needn't stop at two. Since many people build
(to take one example) gcc from source, using an old version of gcc,
the hack would have to be propagated to all current gcc builds in some
way - you can't simply build once and install the binary as the
official C compiler, not in today's distributed society. (If you're
truly paranoid, you might believe that gcc has had the hack in it
since its inception. But some people build gcc using other compilers,
too.)

If you can't trust any code you didn't write yourself, you're left
with Rene Descartes' line I think, therefore I am - it's impossible
to prove anything else, since you can't trust your senses. So go
ahead! Distrust everything and use nothing. Or accept that, even if
you're the target of a huge conspiracy, it doesn't even matter,
because life still goes on :)

Python scripts or applications might not be compatible with Python 3.x
and require 2.x instead.


And the other way around.

I capitalize Free to avoid confusing it with free as in beer.

Yes, you can trust Python. If you don't like the precompiled versions,
you can simply download the source code (plain text files) and build
your own, so any advertising in it could be removed very easily - and
would thus be worthless, so nobody bothers to put any there. Open
Source is different from ad-funded software; both of them cost you no
money, but there's a complete difference in philosophy.

Definitely get the latest version (currently 3.3, soon 3.4). Python
keeps getting new features and improvements.

Yes if you download binaries from the official sources (python.org web
site) there is a reasonable assumption that the binary is free from
malware or viruses.  I've never heard of programmings coming with spam
before ;).  Usually that arrives unbidden in my inbox.

As for trusting python in general, I do trust the python developers, but
recent NSA revelations call just about all aspects of computing, trust,
and privacy into doubt.

Python is available without ads, trojans, viruses, or other malware. 
However, the internet is a big place, and there are undoubtedly some
places which will add their own garbage to the download.

If you get Python from python.org, or from activestate.com, it'll be
safe.  Someone here will be glad to give you a link, once you identify
just what you actually need:

1) what OS are you running?  Actually, we can be pretty sure you're
running Windows, since any other common operating system would have
already included Python.  But you will need to know whether it's 32bit
or 64 bit OS.  You can run a 32bit Python on 64bit OS, but not the oter
way around.  And most people just match the bitness of Python against
the bitness of the OS.

2) What version of Python does that software you're talking about
require?  The two most lkely candidates are 2.7 or 3.3  There are
packages out there that haven't yet ported to 3.x, so you may be stuck
with 2.7.  But if the package is older, you might even need 2.6
