[issue34981] Unable to install Python from web-based installer and executable installer

[Steve Dower]

Steve Dower  added the comment:

When you run the installer, it should create log files in your %TEMP% 
directory. Could you find and attach those here please?

There's a chance it is detecting that your system is unsupported. If you are 
still using Windows Vista, ensure you have installed all available updates and 
service packs, and then try installing Python 3.6 (the latest version, 3.7, 
does not support Windows Vista any more).

[issue34981] Unable to install Python from web-based installer and executable installer

[skycraper]

New submission from skycraper :

I have a PC with 2 HDD with 2 Vista OS at each other. One system is old and it 
has Python 3.7 installed and working successfully. The second system is 
new-installed and it has a problems with running web-based installers and 
executable-installer of the latest Python`s version from there: 
https://www.python.org/downloads/windows/ 

So I can run an install from any MSI-package for every version, but 3.5-3.7 
versions don`t have it. When I`m trying to install wb-inst or exe-inst nothing 
happens: no error window, no system lags etc. 

I suppose that this problem connected with Microsoft libraries or extensions. I 
installed all Visual Studio C++ packages, but it didn`t help. 

Could you tell me which components I forgot to intall.

It might be worth while to look at web2py (http://web2py.com).

Here is a good tutorial: http://killer-web-development.com/

There are a few implementations of Python that generate code that can
run the browser. I'm currently using brython and its significantly
easier than struggling with JavaScript. It's not perfect by any means,
it has its own quirks and bugs but the developer is very responsive, the
product is getting better every month and I like to see the Python
community give it a bit more love

With respect, I don't think it's appropriate to direct a python beginner to 
PyPi.  Far better to direct him to the relevant resources (like Django) and 
focus him on the standard Python interpreter, hopefully version 3.

Besides that, there's the old expression. Premature optimization is the root of 
all evil.  Until Python is shown to be too slow for a given task, it's 
premature to think about speedups like Cython or even PyPi.

While Python can do that, using a web framework to process HTTP requests and 
generate HTML to display in the browser, I don't believe Python is the 
appropriate language for the task at hand.  Most web sites that do interactive 
formula calculations like you describe do it all in the browser using 
Javascript.  No need to have a web server do all that heavy lifting at all.  A 
simple html file would contain everything you need.

Even if you want to use Python to generate the web page and process events, 
you'll still have to master Javascript at some point to make the webpages more 
interactive.

There's a website called Python Tutor where you can write Python programs and 
it will show you the structures built in memory as it executes. It's  very 
useful for seeing how recursive functions work, or any function or class you 
call. It will also work for simple programs and it has an output console you 
can print to.  (Well, it's more like a print window, but it works.) Very good 
for beginners, I used it all the time when I was first learning, and I still 
use it for recursive functions, since PyCharm doesn't step through recursion in 
a clear way.

Building a web site can be done with Flask, Django, aiohttp, or a
number of other frameworks. Generating graphs can be done with
matplotlib. Speed won't be a problem - a computer can do a LOT of
mathematical calculations in the time it takes to request something
over the internet.

Re: Moving to Python for web

[sepatan]

Here, for example, take a look:
http://www.clips.ua.ac.be/pages/pattern

 So, I have been working in PHP for several years but I want to learn
 something new. That something new is Python. But since I'm a web developer
 I want to build stuff for the web.

 I don't want to use Django because it's too bloated, it seem to do
 everything for you. I don't like that. I want to do the plumbing. But at
 the same time I have no idea how I would write something that could handle
 cookies, sessions, post, get etc etc; so I assume I have to use some kind
 of web framework.

 So, can you recommend a minimal web framework that still allows me to
 write in Python? Furthermore, do I even need one? I am currently running
 NGINX and I have UWSGI installed. I'm just worried about how I would
 handle form submissions, get requests and sessions/cookies.

 Any advice would be greatly appreciated.

I am in the same boat as you, I need to rid myself of php, and ruby doesn't
feel right..
I like python for system admin stuff.. it seems everything has python
bindings :)

there are MANY micro frameworks, I have been following these guys for a few
years
http://www.pocoo.org/

specifically jinja2 and flask looks to be the best choice out of all the
options out there

+1.  The Pocoo team makes many awesome things.

 specifically jinja2 and flask looks to be the best choice out of all the
 options out there

Jinja2 is a standalone templating engine, something like Smarty for
PHP.  And Flask is a microframework, which adds on top of Jinja2 (not
mandatory) and Werkzeug (another Pocoo project) to make a nice and
easy webdevelopment base.  IMO it is the best choice in terms of
microframeworks.

But microframeworks are, as the name states, micro.  The big
frameworks include tons of abstractions and fancy features.  Some
people may like them, others may not.  (Those features can obviously
be implemented in the microframeworks on one’s own or through existing
open-source code.)

How are you running uWSGI?  On sane (non-Windows) OSes, I recommend
using the uWSGI Emperor, which will protect you from your website
going down when something crashes.  You run the Emperor through your
OS’s init system (e.g. upstart in Ubuntu, systemd in many others).

Moving to Python for web

[ecazs . net]

So, I have been working in PHP for several years but I want to learn something 
new. That something new is Python. But since I'm a web developer I want to 
build stuff for the web.

I don't want to use Django because it's too bloated, it seem to do everything 
for you. I don't like that. I want to do the plumbing. But at the same time I 
have no idea how I would write something that could handle cookies, sessions, 
post, get etc etc; so I assume I have to use some kind of web framework.

So, can you recommend a minimal web framework that still allows me to write in 
Python? Furthermore, do I even need one? I am currently running NGINX and I 
have UWSGI installed. I'm just worried about how I would handle form 
submissions, get requests and sessions/cookies.

Any advice would be greatly appreciated.

Python in web development

[Sarbjit singh]

Hello All,

I have been using Python as a scripting language for my office tasks. Now I 
have been thinking of using (and learning as well) for web development. For my 
tasks, I need to perform some tasks and report on the web. Now I have no 
experience of web development with Python. So, I want to conform first whether 
Python is best for web development. Python is my personal choice for my 
automation works and I want to extend it for web development.

REQUIREMENT:
I need to develop a html form which would take user input and perform some 
operations (generate intermediate files) and report result on web.

 Some guys in my organization are using Perl for this purpose and thus I 
 could get the setup for free.But I want to learn and use Python as 
 substitute for Perl. (PHP could also be an option. I have worked on PHP once 
 for handling the form data.)

So my questions are:-

1. Can I use Python (I want to use personally :)) over PHP/Perl?

2. If Yes, I want to know the modules that I should learn for achieving my 
requirement. I searched internet and found Python provides CGI, Django etc.

I don't much about Django/CGI, please suggest which module I should learn and 
use.

Thanks
Sarbjit

Re: Python in web development

[becky_lewis]

1) Python is absolutely fine for web development. It's just as good, if not 
better than PHP or Perl for this sort of work (that's my opinion anyway).

2) I've used Django quite extensively and it can certainly handle your 
requirements. You might want to have a look at Flask (http://flask.pocoo.org/) 
as it's not quite as heavy as Django so would possibly suit your needs a little 
better.

There are literally dozens of frameworks you can use.  You could use
straight CGI if you wanted, but I recommend a framework with a decent
templating engine for HTML code generation.

Anyway, a list--not exhaustive--of frameworks can be found here:

http://wiki.python.org/moin/WebFrameworks

Django is one of the most popular.  Web2Py is another.  Though they
might seem overkill, it's well worth it to use them and learn them.
They both have good documentation.  So start there at their individual
sites.

Re: Python in web development

[Michael Herman]

If Python is your personal choice, then it's the *best* for you. If
you are literally just going to be processing an HTML form, then CGI
is your best bet. However, if you think this functionally will grow,
then it's worth learning a web framework.

I would go with a micro framework. bottle.py is a perfect starting
point. I am a huge Flask fan, but it's a little higher level. I have
tutorials here for Flask -
http://www.youtube.com/playlist?list=PLLjmbh6XPGK5pM1QJ8I1ccdGiCTHa1IC8

Also, check out realpythonfortheweb.com for more tutorials.

Good luck! :)

Depending on your needs, you may find something like bottle or Flask a 
better choice then.


Django can be scaled down a lot, but it's a full-featured framework at 
its heart. Bottle is pretty minimal (IIRC it doesn't even come with any 
templating). Flask is somewhere in between as it bundles Werkzeug (a 
pure WSGI framework) with Jinja (a template library) with some glue code.


I have used Flask in the past but often found myself implementing half 
of Django anyway, which is why I eventually switched. When I only need a 
bare API with no database and without templates, I usually go for Bottle 
these days.


If you feel like coding closer to the metal and care more about 
performance than readability, you might also find Twisted useful.

You can pick and chose which parts of django you want to use.  You don't 
need to use any of the Django model stuff.  You don't need to use any of 
the template system.  You can tear out all or most of the default 
middleware.  At that point, about all that's left is the route parser 
and dispatch code.  The nice thing about this is that as you 
incrementally discover which pieces of it you really do need, it's easy 
to pull them in.

That being said, we've made a lot of use of Tornado for small 
stand-alone web services with just a couple of routes.  In retrospect, 
it's unclear if there's any justifiable argument for why we use both 
Tornado and Django, other than hysterical raisins.

Well PyPy is just an implementation of Python among many others (but limited to 
version 2.7). It is not a web server. If you want to make PyPy interact with a 
web server (such as nginx) you have to use a special protocol such as WSGI or 
Fast-CGI. For best performances you can for instance use uWSGI that integrates 
well with nginx but for this you have to recompile nginx. As you see it's a bit 
complex, you should read the wikis. May the Force be with you.

For any sort of web-based real-time game, here's two things to avoid:

1) Snoopability and modifiability of crucial data. Everything should
be stored on the server, so that if anyone fiddles, all they do is
break their own client so it has to reload from the server.
2) Massive waste of resources due to unnecessary frameworks/facilities.

I play a lot of Flash games, and right now I'm playing one that has
coped poorly with a miniature slashdotting. A spike in popularity
resulted in a spike in server lag. I fired up a little packet sniffer,
and discovered that every time you do anything in the game, the client
makes a new POST request to its server. Why?! It's not that hard to
hold a socket connection open!

In another context, a similar issue - not a problem as yet (that I
know of), but would be if the system were to be slashdotted. A server
whose sole purpose is to handle script-instigated requests (using HTTP
POST for its transport) sends back a Set-Cookie header with a session
id. This implies that the server is holding session data for all these
clients that are never going to send that cookie back. The server
appears to be IIS with ASP scripts, so presumably stateful sessions
are enabled by default, so it's costing memory and processing to hold,
then discard, all those useless (and probably empty) session state
tags. And presumably many MANY other servers have the same thing.

What's YOUR framework doing that you don't need, and how much is it costing you?

Yeah, I was trolled bad. :)

using python in web applications

[Littlefield, Tyler]

Hello all:
I'm curious if there are some good solutions for using Python in web 
applications.


I'm not feeling particularly masochistic, so I do not want to develop 
this project in PHP; essentially I'm looking to build a web-based MMO. I 
know that you can use nginx with Python with servers like Flask, but I'm 
not really sure how well all of those work. Since this will be a game, I 
can expect quite a few users; I've already got quite a lot of interest. 
I don't much care for PHP, but the thing that can be said for it is it's 
pretty quick. How does Python compare? Are there some solutions (I was 
told about PyPy today) that would be quicker that I could still use for 
the web app? I'm also curious what databases are suggested? I've always 
done most of my work in MYSql, but from what I understand postgresql is 
becoming more popular to.


Thanks all for the input,

 ahh paul bonser _did_ make an attempt to write a web browser in
python: he got quite a long way but nobody helped him out,
unfortunately.

 i did actually get grail browser up-and-running again, under python
2.5 and then 2.6 - it actually works, hurrah! :)

 the list of client-side (assuming you meant web browser client, sid)
python programming environments is actually really quite long.. and
some of them very very obscure :) i maintain (as i find them) a list,
here:

 http://wiki.python.org/moin/WebBrowserProgramming

 the one that i have the most respect for (despite its DOM TR2
compliance only, and the obscure bug that most people will never
encounter) is python-khtml.  KHTML aka Konqueror's web browser is the
granddaddy of webkit after the toerags from apple got their grubby
mitts on it, and i do wish that KHTML got more love and attention,
because it's a proper true free software *independent* web browser
engine that is truly developed by a free software community, not a
bunch of corporate lackies with a commercial axe to grind.

 there is quite a lot of mileage to be had from ironpython, because of
course it translates to CLR (.NET) - as a result you have things like
appcelerator (titanium).  sadly you'll probably get that running under
mono at some time when hell freezes over, but that's another story.

 the other one that's worth a laugh, ok maybe a snort, is the mozilla-
funded project back in 2000 to add support to firefox for  script
language=python / which actually damn well worked - properly -
except that it resulted in a whopping 10mb plugin (because it was the
entire python interpreter in a firefox plugin, that's why!) and was
only available for firefox.  oh, and building the dependencies on w32?
jaezzus h christ on a bike was it a bitch.  to give you an idea: the
last people who attempted it were novell, some time around 2007.  to
get an accurate date, look up the release date on xulrunner 1.8.

 anyway - bottom line: there's a hell of a lot (including pyjamas of
course, yaay!) but it's all pretty obscure esoteric stuff and you do
have to be a bit off your head to consider using the various options
available.

 More seriously: except for the old proof-of-concept Grail browser, no
 known browser uses Python as a client-side scripting language.

 There are three relevant projects:

1) Pyjamas - translates a dialect of Python 2.x to Javascript, and provides
a widget set that allows the same code to provide a web GUI and a desktop
GUI, using a desktop-like API

2) Emscripten - which is CPython 2.x itself (and theoretically, 3.x?)
compiled into Javascript using LLVM's C frontend and an LLVM bitcode
translator that creates Javascript code

3) Pypy - had a Javascript backend, but that was removed from the website in
2010 (?)

Of these, Pyjamas is probably the most useful today.  Emscripten reportedly
crashes some browsers, and Pypy seems to have lost interest in Javascript.

There are various options, the simplest is using a full blown web
framework which simplifies about 90% of the work and you only need to
code the logic related to your app. Two of the most popular frameworks
are django [1] and turbogears [2].

You can also go more low level by designing your own framework from
scratch which is something the bigger shops are doing like youtube.

In any case there is a wiki page that you might find useful [3].

Python does not have a local web server. Python's standard library
does include a basic server class that can handle HTTP, if you wish to
use it.

But this is not a standalone sort of server that you configure and run.
It is a piece of code in a library, you instantiate and use. You
configure it by writing code. If you would like to configure it via a
config file, you have to write that. Code to read the file, code to set
up the server class based on it, and such.

Guide you? You're asking too much. Too vague. I wouldn't even know where
to start. You really need to go curl up around the docs and spend some
time reading it-- BaseHTTPServer, SocketServer, BaseHTTPRequestHandler
are where you get all the information you are looking for.

I don't think that number is fair for Python. I think a well written 
Python web server can perform in the same ballpark as most mainstream 
web servers written in C. Especially Apache, which really isn't a top 
performer. And I'm pretty sure a well written Python server can 
outperform a badly written C based server easily.

The order of magnitude I gave is based on real-world testing. You are

Recommendation for small, fast, Python based web server

[python]

I'm looking for a small, simple, fast, Python based web server
for a simple, client side application we're building. We don't
want to distrubute and support a real web server like Apache or
Tomcat or depend on the presence of local web server such as IIS.
The application in question will service AJAX requests from a
browser.

We're not looking for a web framework like Django, Plone, etc.

I've looked at the web servers that come bundled with the Python
standard library[1] and they are too slow. I suspect this is
because they don't maintain a session between the client and
server, thus every GET/POST request repeats the session setup and
break down process. Or they might be based on a polling model?

Here are the other Python based web server implementations I'm
aware of:
- cherrypy
- web.py
- twisted

Any recommendations appreciated (Python 2.6 preferred but open to
Python 3.1 options).

Thanks!

I'm not sure what caused the slowness you've experienced -- using 
Python in a CGI environment requires starting the Python 
interpreter each time.  However if the interpreter starts just 
once, I've not had notable performance issues for low-volume 
sites (using the BaseHTTP builtin).  For higher-volume sites, you 
might reach for Twisted which WebStack supports as well.  I 
believe both WebStack and Twisted are redistribtable as needed.

Thanks for that recommendation.

 I'm not sure what caused the slowness you've experienced (... with running 
 local versions of Python web servers)

Thanks to a past post by Christoph Zwerschke c...@online.de, I was
able to identify the problem.

Windows (XP, Vista, Windows 7) tries to do a IPV6 connection which times
out after a second followed by an IPV4 connection which is almost
instantaneous. Apparently this is a known problem that is a Windows
issue [1] - not a Python problem.

Two workarounds:

1. Use 127.0.0.1 as your URL vs. localhost 

-OR-

2. Edit your Windows hosts file (c:\windows\system32\drivers\etc\hosts)
and create a virtual domain name, eg. put the following on a line by
itself:

127.0.0.1  mydomain.someext

And then use mydomain.someext vs. localhost

Note: Editing your hosts file requires admin rights under Vista and
Windows 7.

Depends what you mean by suffer.  Performance always decreases as size
gets larger unless you take specific steps (such as better algorithms or
bigger hardware).  Using indexes should give SQLite reasonable
performance; you can always upgrade to a faster SQL implementation or
switch to another kind of storage.  But honestly, until you get to
millions of records, you should be fine with SQLite.

Hi,

1. Open a certain web page and find the first text box on the page, and
put this text into the form.
2. Press the submit button, and wait for the result page to load.
3. Click on the 15th link down the page.

Use the module mechanize. It will mimic a browser, and allows you to 
navigate to pages, fill in forms  submit them.


And with lxml or BeatifulSoup, you can extract the link you need to 
press, and then make mechanize visit it.

Well, what seemed a very daunting task at first, proved to be quite
easy, after a little bit of research. Thanks very much, I've written my
script, and it works correctly, using the mechanize module.

Thanks for everyone's help

No, you don't need any text mode browser. It's much easier to do with
modules from the Python standard library.

 1. Open a certain web page and find the first text box on the page, and
 put this text into the form.

I assume you know HTML and HTTP.

You can use urllib or urllib2 to submit the form.

 2. Press the submit button, and wait for the result page to load.
 3. Click on the 15th link down the page.

You will then get the returned HTML from a function and you will have to
parse it for the link you're interested in. There are many approaches to
get there. Manual parsing, regular expressions or one of the XML parsers
in the standard library (etree is the easiest).

 So, how do I do this, can anyone point me to some docs or modules that
 may help out here?

While all of this may seem overwhelming at first, I guess the solution
can be written in 20 - 30 lines of code.

best performance for storage of server information for python CGI web app?

[davidj411]

I am wondering what will give me the best performance for storing
information about the servers in our environment.
currently i store all info about all servers in a single shelve file,
but i have concerns.
1) as the size of the shelve file increases, will performance suffer ?
2) what about if 2 updates occur at the same time to the shelve file?
when a shelve file is opened, is the whole file read into memory?

if either scenario (1 or 2) is true, then should i think about
creating a shelve file per server?
i was also thinking about using SQL Lite with one DB to store all the
info.
with this option, i would not have to worry about concurrent updates,
but as the file size increases, i could expect performance to suffer
again?

I am running Python 2.6 CGI scripts on Apache web server on windows
platform. they interact with the current shelve file to pull info or
request info from a python service which will go collect the info and
put it into the shelve file.

 with pyjamas, as mark mentioned previously - but what mark perhaps
wasn't aware of is that with pyjamas-desktop you can have _both_.

 you can have the _exact_ same python application _either_ be compiled
to javascript, and be a web application, _or_ you can run it under
pyjamas-desktop, as pure python.

 so you can have a pyjamas app do _both_ jobs.

 for some examples that look like the kinds of things that you would
expect, see:

http://pyjs.org/examples/timesheet/output/TimeSheet.html
http://pyjs.org/examples/employeeadmin/output/EmployeeAdmin.html

both of these use http://puremvc.org (python version, not javascript
version).  both of them work under pyjd.

Very much so.
The web frameworks, Django  TurboGears are quite powerful and can be
used to do what you just now mentioned.
Check out Django - esp if the application is database centric. It has
very good documentation and a free online book - djangobook.
