I'm building an app for a small business so I've to work with currencies, decimal numbers, etc... My goal is to create something like pulseapp.com.
I've searched for opensource projects to look and the only thing I had found was django-cashflow. This app uses python-money.
I've read some of the code and the ways it's coded seems a bit weird to me and it's not fully complete.
Is the app worth to take a deep look?
Does anyone know about another similar app?
Is the task difficult or a begginer like me could find a way to code it himself?
If you're dealing with currencies, you might look to satchmo's codebase. http://www.satchmoproject.com/ They're the current front-runner in Django e-commerce. I'm sure they have money modules.
Here you have something you might be interested:
Tryton with Django
I started to use python-money in an application a couple years ago, but had to abandon it due to some problem. I apologize for forgetting the exact problem, but I do remember for our use case it didn't make sense anyway... we just needed decimal fields.
I'd also be wary of django-cashflow not having any activity for 2 years, although the project is small enough it should be easy enough to fix any problems yourself.
For existing Django accounting apps I would suggest enhancing, or at least looking at, minibooks. NOTE: the license is AGPL v3 which could make it unusable for your environment.
Another road to travel would be to investigate porting OpenERP (also GPL IIRC) from Python/GTK to Django. Tryton might also be a starting point, it's GPL3 and IIRC a fork of OpenERP.
I've written a framework to help speed up the development of customised commerce aspects of django sites: Rollyourown shopping.
It lets your write your models yourself, and uses a declarative syntax to define a summary class, which handles calculating totals, caching and formatting values etc. It's pretty fast for my use cases, and very flexible: I've used it for online stores, billing for consulting-services and auction sites :-)
The current version works fine, but I'll be releasing a '1.0' version later this month as I decide on the final (stable) API details (names etc) and maybe some external reviews.

So I'm learning Python and beginning to grasp the fundamentals. I want to start a project that seems slightly over ambitious for my current knowledge level but I think I can do it bit by bit and it will look good in my portfolio.
Basically, I'd like to create a web application that generates a grid and allows the user to create rooms to scale. Dragging and dropping pieces of furniture to visualise how much space they will have between various pieces of furniture and checks if pieces will fit. Also I'd like the user to be able to save real furniture for example, using the Ikea website that will, when they're finished, generate a basket containing links and pictures to the items they have chosen and give them an idea of total cost.
It feels daunting starting out, what modules/libraries would I use to get this going? I'd like it to be a web app that is mobile friendly ideally?
Thanks in advance.
Making interactive web apps like that are not really within Python's capability.
On the web, Python (via Django) is good for back-end things and making websites, but for client-side interactivity like you are suggesting, you need to use Javascript.
There is a tool called Brython that lets you write client-side Python and then it will convert it into Javascript for you, but it is quite complicated.
I would suggest picking another project for Python (here is a great list), or if you want to continue with that furniture idea, then picking up some JS, React, and using a library like react-dnd would be a good starting point.

I'm new on the programming world using python, so i have some questions for desktop aplications development.
1. Im currently using pycharm as my idle, can i use it for my purpose?
2. Can i use peewee as my ORM and Tkinter for my GUI? or should i just use Tkinter?(Recommendations are welcome)
3. I'm planning to use Sqlite3 as my database, should i keep this idea?
My further plan is to make an application to store the networks equipments in an enterprise, like desktops, laptops, switches, etc.
And also get some reports like to wich user belongs a desktop or laptop, wich kind of license does the equip has, a bitacore to store all what happens to an equip, etc.
I'm very new on this world and have been reading, practicing and taking courses for 3 month by now to understand concepts, learn about programming, etc.
Tahnks for the tips.
If you know Tkinter then stick with it, otherwise consider a higher level framework like PyGUI, PySimpleGUI or QT (Arguably not that simple, but plays nicely with PyInstaller). You will definitely be able to keep using SQLite3, as there is an existing binding in python 2&3.
If you plan to deploy this app, then you need to consider if speed is going to be a problem. Python is great but fundamentally quite slow. You can use things like Cython or PyPy to speed it up, but this can get complicated when you look at using a packager such as py2exe or PyInstaller for distribution.
best of luck.

Just wondering what the best way to get started learning Python to do backend engineering is and what the best framework to learn for it is (Pyramid, DJango etc...). I have done algorithms in school, build iOS apps and know Java, Scala, OCaml (lol), Racket (lol) and Objective C. I currently have to use Parse for my apps but want to build backend engineering skills. I'm thinking I might as well do the code academy course but the ones I've done from them don't seem in depth enough. Maybe an Udemy course? I want to get good enough to get an internship in backend engineering next summer. Need to find the best resources to do that before then. Thanks!!
While that question is quite open-ended, I personally think using Pyramid right out of the gates was super helpful. One of the pillars of this project is documentation, and their ideology is that you pay for what you use, giving developers the ability to customize their web applications to a good extent. Check out the docs here http://docs.pylonsproject.org/en/latest/docs/pyramid.html!
They also have excellent tutorials that guide you through the traditional "Hello, world!" application, and also more advanced stuff, like how to work with sqlalchemy to utilize databases in your web applications. This is how I learned essentially all of what I know about the framework! I would definitely recommend this, especially if you are just looking to start out and get your feet wet. But, as I said, this is my own opinion, and am sure that there are others with differing opinions on the matter. Best of luck!

I realise that web application frameworks are well documented, yet having tried 2 Python frameworks and found that are neither are suitable for my task, I hope you'll understand the need for this question.
I'm looking for a lightweight, "micro" framework for Python with the following features:
Basic HTML layout management
Features for HTML forms, tables etc.
Authentication and session management
Preferably integrable with mod_wsgi
Seamless importing of packages
That's it. You may ask why I need a framework for this at all - I don't. But it would save a lot of time, and I'm very surprised that I can't find something like this.
I'm reasonably advanced in Python but want to deal with the HTML and authentication as effortlessly as possible. I have a lot of existing code that I would like to be called from within the framework. I don't require an ORM or DAL, I would like my existing classes to continue to use their own MySQLdb driver. Inevitably, for authentication to be handled, an ORM or DAL will be included, but I just won't use it for anything other than authentication.
I have tried web2py and Grok, both supposedly lightweight, configuration-free frameworks, yet both were far too high-level.
Thanks in advance.
You should have a look at flask.
It comes with jinja as a template language.
It doesn't contain any ORM.
There are lots of well supported extensions for sessions, forms, ORM, etc.
You can also try WebPy.
The full (?) list of python web frameworks is given here. This slideshow compares 10 micro frameworks and should be of intrest. Not all of them will tick your boxes but at least it should give some hints as to their pros/cons.
I propose looking into web.py and Tornado.
Web.py is incredibly simple to use with a power of a full web framework.
I used it for OData implementation with great success.

With 145 forks, 125 open issues, and the last release almost 2years ago, django-piston appears to be approaching abandonware and since the project I'm working on is likely to be a big one, I'd like to standardise on something that's going to be around for a while. Is there something resembling a consensus in the Python/Django community regarding a preference for REST API services? Even if it's one of those 145 forks? Ideally, I'd like to find something that plays nice with #jacobian's REST Worst Practises
check http://djangopackages.com/grids/g/api/ (django-tastypie looks very promising)
I also don't like Piston very much. Don't misunderstand me. It is (or was) a good app, though it has its issues. The main problem I had working with it that it hides Debugging information coming from django.
If you are absolutely unsure about what to use roll your own. With django 1.3 and class based views you got already a good way to add an API like this. If you need OAuth or other authentication methods you can simply check existing ways in piston or other apps and use them.
Two other REST packages that may be of interest :
http://django-rest-framework.org/
http://benoitc.github.com/dj-webmachine/index.html
It is worth mentioning about
django-tastypie
This is getting faster acceptance than the others.
Django Piston project seems to be abandonned.
Django rest framework has taken a large advantage with its second version.
Note that this is valid for now (2014), time may decide different.
