Problem importing libraries installed with PIP in Eclipse
Hi guys, I'm using Python 2.7.5 64 bits and I have a problem when importing libraries that were installed via PIP when importing them inside Eclipse (version 4.3.1). Outside Eclipse (directly in Python's shell) everything works fine, here is an example: >>> import numpy # installed from repositories >>> from numpy import array >>> import pybrain # installed via PIP >>> from pybrain import Network >>> Everything works outside Eclipse. But inside Eclipse I can't import libraries installed via PIP using "from x import y" format, it will give an error. The only way I can import libraries installed via PIP is using "import x" format. Here is an example: import numpy # no errors (installed from repositories) from numpy import array # no errors import pybrain # no errors (installed via PIP) from pybrain import Network # gives the error below Traceback (most recent call last): File "/media/arquivos/pybrain_import_test.py", line 4, in from pybrain import Network ImportError: cannot import name Network I suspected it could be related to virtualenv, but here is a print screen (http://imageshack.com/a/img534/4307/3x0m.png) of my Python's PATH. The directory /usr/lib/python2.7/site-packages where PyBrain is installed is already in Python's PATH inside Eclipse.

Re: Problem importing libraries installed with PIP in Eclipse
It's solved now, oh my god I was so stupid! I created a package named "pybrain" for testing PyBrain module, so obviously when I tryed to import something from PyBrain library, Python would import all modules from this personal package I created. The problem was not being reproduced outside Eclipse because only within Eclipse my personal workstation directory (which contained the personal package "pybrain") was visible. The solution was simple: I just deleted the personal package named "pybrain" and now everything is working. Thank you very much for your help! -- https://mail.python.org/mailman/listinfo/python-list
Password validation security issue
Hello everybody, I implemented a password validation with a Python 2.7.5 script
in OpenSUSE 13.1. The user calls it passing 'login' and 'password' as
arguments. I made a dictionary in the format hashtable = {'login':'password'}
and I use this hash table to compare the 'login' and 'password' that were
passed in order to validate them. The problem is that any user who can execute
the script will be able to read it too (since it must be read by python's
interpreter), and this is causing some security issues since any user can
access all other users' passwords if he opens this script and reads the code.
My question is: is there a way of preventing the user from reading the script's
content? Is there any strategy I could use to hide the passwords from the users?

Re: Password validation security issue
I would like to thank every one who posted a reply. I learnt a lot from you,
guys! I appreciate your attention and your help :)
I took a class on Computer Simulation last year. It was told that deterministic
(pseudo-)random numbers are excellent for simulations, because they allow
debugging and replication when using a seed(). But it was said that
deterministic random numbers weren't indeed suitable for encryption and
security issues in general. For this purpose, non-deterministc stochastic
methods would be more indicated. I learnt a lot about deterministic random
numbers generation in this course, like using Mersenne Twister algorithm, but I
learnt nothing about encryption, since it wasn't in the scope of that course.
Could you suggest some introductory material concerning encryption? I have an
intermediate math background (calculus, linear algebra etc) and I'm willing to
learn more about security matters.
One last thing, about my original question. So, the only way of encapsulating a
Python script content is to code a simple binary program to call it?
Regards,
Renato

Re: Guido at Google
For what is worth, all of the native administration tools of RedHat (all versions) and Fedora Core are written in python (system-config-* and/or redhat-config-* ).

python, threading and a radio timer
Dear all, I found this nifty article on how to record your favourite radio show using cron and mplayer: http://grimthing.com/archives/2004/05/20/recording-streaming-audio-with-mplayer/ Because I couldn't get the date in the filename (and was too lazy to look into sh/bash manuals), I decided to use Python. It was a good choice, because I decided to improve the timer - learning some more Python along the way! So, the idea is: - cron runs the script at a specific time - the script starts mplayer, and will keep checking the clock until it's time to kill mplayer - after mplayer has exited, oggenc is started to turn the raw WAV into ogg - and finally the remaining WAV is deleted This basic setting is quite easy, and I used os.spawnvp(os.P_WAIT,...), along with another CRON entry to kill mplayer. But then I got more ambitious: I wanted the script to keep checking if mplayer was alive - in case the connection goes down. Moreover, I would rather have the script stop mplayer than cron. At this point, I thought I should get some professional help... :) What is the right way to go? Would threads be overkill? If so, where can I go about looking for process control/management without delving into complex daemon architectures? So, rather than asking for code, I'm looking for guidance - this is a didactic experience! Cheers, Renato -- http://mail.python.org/mailman/listinfo/python-list
Re: installing python on a server?
You mentioned using python for web apps: with which framework? (TurboGears, CherryPy, Subway, Django, whatever) Or only for cgi? With which web server? (Apache, Twisted, Zope, etc.) On which linux platform? (Slackware, Debian, Fedora/RedHat, Suse, etc) I think you'll have to think about other questions before.

Vim simplifies this immensely: set tabstop=4 set shiftwidth=4 set expandtab set smarttab set autoindent AFAICT this gives me all spaces, 4 spaces indent, tab inserts spaces and backspace over a block of 4 spaces deletes all of them (just like deleting a tab). -- Renato Usi Fedora?

Maybe I'm just nitpicking, but please! wxWidgets apps look ALMOST native on windows (combobox and similar widgets are emulated, and look really bad), and they sure _don't_ look like gnome apps on linux (gtk maybe, except for those custom widgets, but surely not gnome).

Uh... no, not on linux. Try this: $ touch foo.txt $ gedit foo.txt & (write something in it and save, but do not close gedit) $ gvim foo.txt (write something else in it and save, but do not close gvim) $ rm foo.txt All this without having "the file is in use" errors, because well... only windows has those :-) Oh, and btw: you'll notice that gVim is smart enough to notice that the file is no longer there, or that it is there but is more recent than his working copy (if you re-edited with gedit, for example). -- Renato Usi Fedora?

AFAIR the linux package for wxpython does not require wxWidgets at all (it's embedded). As for the obsolete gtk look for a "gtk+" package, not for the "gtk" which is the up-to-date gtk2 package.

As in "protecting your code from prying eyes"?
Then java is exactly like python: I can distribute a fully functional
python program using only .pyc or .pyo files (unreadable) just as I can
distribute only .class files (or jars) in java.
And reverse engineering ("de-compiling") both is damn easy. The produced
code won't be beautiful, sure, but don't rely on it if you want to keep
your code secret (for whatever reason).

And it is also HUGE, so anyone NOT having it will think twice before
downloading it only for your app. Python on the other hand is installed
by default on all linux and OSX machines, and on windows you can use
py2exe and produce packages of 2-3MBs (correct me if I'm wrong) with
everything bundled.

It's pretty much the other way round: java CANNOT be included by default in any (free) linux distro for license reasons, and it CANNOT be included by default in Windows as a consequence of court ruling: Microsoft is actually _not allowed_ to include Java. The only system (apart from solaris, I guess) that has a JVM by default is OSX, and it's _NOT_ sun's one, but the internally developed one. -- Renato Usi Fedora?

IDE for GUI Designer
Guys, is this, I wonder if there is an IDE with native support for the development of GUI's such as Netbeans with Swing, Visual Basic, etc., already tested the Boa Constructor, and PyQt, but did not like what I'm looking for is an IDE "all in one", ie power encode and draw the screens of the program, someone indicates some?, but what I would like to know everything together with an IDE: Coding + GUI (via visual elements) without the need to import or export anything, like so: I want a button, I click and drag it to a window, give two clicks and encode their actions, understand?
