Currently, i want to implement a trading system for steam games (with python).
So, i searched github, but sadly, there are only
https://github.com/Jessecar96/SteamBot
https://github.com/Jessecar96/SteamKit2
Yeah, they works good. But they are C# -- don't tell me python can't do this :).
So, i want to start with the steamkit part. I thought it's not difficult(maybe just some web-apis), but when i kinda review the code of SteamKit2, i find it seems use TcpConnection to Steam Network, don't know how they get the protocol.
Does anyone has any idea about this, i think about use python load steamkit2.dll, but im really noob with C#
You don't want to use the SteamKit2 port on that repository. It is a branch (and an out dated one at that) of the official SteamKit2 repository. It also looks like they are attempting to get rid of the branch based on this issue discussion.
To answer your question, there is a port of SteamKit to Python. It is called PySteamKit and is written by one of the contributors to SteamKit2.
Unfortunately, there doesn't seem to be much documentation in the Wiki of either the official SteamKit or the Python port on how to use the package. You may have to look at the Samples provided by SteamKit which are in C#.

i'am just learning about raspberryPi. how can i communicate raspberryPi with database, so that can raspberryPi send message/sms using gsm module?? and how the Raspberry Pi read databases mysql from different tables that could be sent in a single sentence using gsm?
I hope any suggestion given to me from friends in here
Thanks
Nice first question adew!
To improve the next future question you make please read: https://stackoverflow.com/help/how-to-ask
I will take the time to try answer your question, because I suspect that there is more people out there with the same ideas as you.
To start with
GSM module communication:
This question has many different answers and the answer depends on what hardware you will use. There is no standard in this area.
To give you some options;
https://www.sparkfun.com/products/9533
https://www.adafruit.com/products/2636
Sparkfun will provide you with a detailed datashet & Adafruit even has a detailed tutorial. The drawback with the Adafruit tutorial is that it assumes that you are using a arduino (Not a big problem)
Both of the above modules are capable of UART communication, something you easily can access with a RaspberryPI and
http://pyserial.readthedocs.io/en/latest/pyserial_api.html
https://github.com/WiringPi/WiringPi-Python
Personally I have used WiringPI before and it is easy to start with and has a bunch of active maintainers on IRC.
To wrap up the GSM-part. Consult the manual for that particular device you are going to use. That is the only way you will know what to send and what you will receive from the module.
Database querys:
Are you using a existing database or are you going to create your own from scratch?
Even that part of the question is to broad.
If you are going to make a new database just for this kind of application I might suggest using
https://www.sqlalchemy.org/
It will give you a nice little ORM tool. It will make it easy for you to insert and fetch data that probably matches how you want to work with the data.
If the database is a existing MySQL database
https://dev.mysql.com/doc/connector-python/en/connector-python-examples.html
Well again, consult the manual.
To wrap this up.
This was a very lengthy post, that gave you almost nothing about almost everything. This is why people down-votes a questions like the one you made. Most people dont have the time to give this kind of answers.
I suspect that the next question you make will be related to any of the above topics.
Try to be precise
Give a piece of code that exposes the problem you have
One problem at a time
Happy hacking & have a look at https://raspberrypi.stackexchange.com/ !

I'm using twisted to create a server.
Problem is, I must protect my code. Since I don't want to publish it, I'm not really interess into obfuscation or compilation of the python code.
My problem is, my twisted application must run with root uid and a lot of people have root access to this server.
I don't care if they can read it, but I want sure they can't modify it!
What is the best solution, knowing I'm using twisted? I've seen in twistd, tapconvert and mktap that twisted can "encrypt" my code, but I didn't find any good documentation about that.
Anybody to help me?
Thanks in advance for any answer =)
Have a nice day!
/!\ EDIT:
I got another question, I've wrote my code following this part of twisted documentation: http://twistedmatrix.com/documents/current/core/howto/application.html so I launch my server using a command like twistd -y server.py --logfile ...
Since I'm doing that, I assume I can't use software like cx_Freeze to hide my code right ?
You have a number of problems here.
my twisted application must run with root uid
This is bad. If there are vulnerabilities in your application, then they will be made more serious by running as root. You should consider finding a way to not run as root. For example, if you only run as root so you can bind to a low numbered port, consider using authbind instead.
a lot of people have root access to this server
Perhaps you should limit privileged access to those people who actually need it. If that isn't an option, then perhaps you should at least limit access to people you can trust. Someone who has root on a machine can do anything they want on that machine, and defeat any scheme you dream up.
I don't care if they can read it, but I want sure they can't modify it!
You should ask them not to modify it, then.
I've seen in twistd, tapconvert and mktap that twisted can "encrypt" my code, but I didn't find any good documentation about that. Anybody to help me?
You shouldn't bother trying to use the encryption features of twistd and mktap. These don't prevent anyone from changing your code. At best they might prevent someone from reading some of it. As you said, this isn't even your goal. Even if it were your goal, someone with root access will be able to decrypt these files easily, so it doesn't even help there.
If you give code to someone, expect them to be able to do anything and everything they want with it. If you put code on a server, you are effectively giving it to everyone with root access to that server.
So, stop thinking about encryption and other technical issues and think of some other way to achieve your goals - fire the untrustworthy administrators, use an appropriate license on the code, get an actual contract, etc.
AFAIK, there is no way to prevent a root user from modifying a plain text file. Root is just that, they can do anything they want with it including modifying. Why do so many people have root access to the machine anyway?
If you're concerned, you really have two options:
Encrypt the files in whatever way you want (I don't know if Twisted does it or how)
'Compile' the code for your platform. There are a few Python compilers out there but I don't know if they work with Linux. I'm a free software guy so I want people to read and modify my code. Protecting it doesn't concern me.
I guess you do have a third option of protecting it legally with a license. But if they violate your license then there's the cost of taking them to court over it.
Not many options. Sorry.

Can you guys please tell if building my own birtviewer like reporting tool but using python is a crazy idea. The company I'm working now, we are using birtviewer to generate reports for the clients, but I'm already getting frustrated tweaking the code to suit our client needs and it's written on massive java code which I don't have any experience at all. And they don't want to mavenize birtviewer, so every new releases I have to manually update my local copy and mavenize it. And the fact that it is really owned by a private company worries me about the future of birtviewer. What do you guys think?
Sure. Write it. Make it open source and give us a git repo to have a little look... Honestly if the problem exists solve it.
I'm planning to develop a GUI application that uses curses. The idea is to provide an extra interface for a web interface, so that everything on the web site could also be done via the UI.
Basically, it should be platform independent: the user would have to SSH to the server after which the UI would automatically take over.
First of all, is this doable? As far as I understand, it would be platform independent as long as the end-user had the proper terminal software installed. Correct me, if I'm wrong.
I was planning to use Python for this, as it is the language I'm the most proficient in. Python comes with the ncurses library and Urwid, which I've been told, is quite good.
After having a quick test with Urwid, I had some problems. The thing is, I'm quite worried that I won't find answers to the problems that I will encounter down the road because apparently curses UI-s aren't all the rage nowadays. Documentation and examples are thus quite scarce.
In conclusion, should really I embark on this and quit my whining or drop the idea altogether? Any other suggestions?
It's certainly possible, and curses-based applications are still written regularly (e.g. PuDB is only 14 months old) although maybe not very often.
Did you try asking questions on the Urwid mailing list and/or IRC channel?
oh my, wouldn't this be a dream!
i've seen a couple of things out there to varying degrees of success.
Morticious Thrind: http://thrind.xamai.ca/
future death toll: http://f-dt.com/?wptheme=wp-cli
wordpress yadda yadda, this could be as simple as a 960/blueprint CSS, prototype.js, and a oneliner:
//TODO: Implement useful functionality && unit tests && documentation
//TODO: read
try { eval($F(x)); } catch (e) { panic(); }
BUT! this type of thing is pretty radical. i mean- ANYTHING can happen on the canvas of a web-browser these days, but any terminal emulator or lynx serves this purpose with flare.
also be sure to check out: https://stackoverflow.com/questions/472644/javascript-collection-of-one-line-useful-functions
the real question is what sort of software you plan on ncursing (sic,pun,etc.)-- it probably already has some rather useful command-line interfaces (sh).
It can be done but it's a struggle. I would recommend improving the web interface. You can use JavaScript to add keyboard shortcuts, for example, which can be very helpful for a faster workflow (see Gmail's interface, for example).
Is it possible to make python run on your homepage? I know, this is a really stupid question but please don't pick on me for my stupidity :)
If it is possible, how? Do you have to upload/install the executing part of Python to you website using FTP? or...?
Edit: Just found out my provider does not support python and that shell access is completely restricted. Problem solved :)
Everything depends on the hosting provider you use for your homepage -- do they offer Python among their services, and, if so, what version, and how do you write server-side scripts to use it (is it CGI-only, or...?) -- if not, or the version / deployment options disappoint, what do they allow in terms of giving you shell access and running long-time processes?
It's impossible for us to judge any of these aspects, because every single one of them depends on your hosting provider, and absolutely none of them depends on Python itself!-)
Yes, you can. I don't know exactly how but I know it is possible. Mabye look into this website:
https://trinket.io/
This website lets you do this. I sent them a message to see how they do it so I will update this to let you know after they respond.
Python is a scripting language, though it is used gracefully for building back end web applications.
