using script as both library and executable in python packages
Make it a normal .py module so it can be imported, and define an entry point. Automatic script creation will take care of creating a script in bin that will call the entry point method.

how to honor the parent logging namespace when importing python modules from entry points
How is the plugin supposed to know whether it's part of application foo as opposed to application bar? If you don't want your plugins to be part of the foo namespace, you can just attach your handlers to the root logger and you won't get the message about "no handlers could be found".

python packages -- overriding built-in packages and the dreaded "Module xxxx was already imported" warning
Rename myprogramxlrd to myprogramfrozen_xlrd. Then import it with try: import xlrd except ImportError: import frozen_xlrd as xlrd Alternatively, you could tell Python to silently ignore this particular UserWarning: import warnings warnings.filterwarnings("ignore", message="Module xlrd was already imported", category=UserWarning) Place this early on in the program, before scikits gets imported.

Does virtualenv isolate python itself + python packages, or just python packages?
Virtualenv installs python, but it's installed in the bin directory of the virtualenv you created. Therefore you need to run it with ./bin/python. You can also "activate" the virtualenv by running source bin/activate Which will put the virtualenvs bin directory first in the path (and do some other trickery I think) which will make the virtualenvs Python the default Python, so you can start it with just python. But this is not necessary.

Plot missing points for complicated 3D list of points - Python
The general approach that you linked to will work fine here ; it looks like the question you're asking is how to apply that approach to your data. I'd like to suggest that by factoring out the data you're plotting, you'll see more clearly how to do it. import numpy as np y_data = [ [[a,0],[b,1],[c,None],[d,6],[e,7]], [[a,5],[b,2],[c,1],[d,None],[e,1]], [[a,3],[b,None],[c,4],[d,9],[e,None]], ] x_data = [0, 1, 2, 3, 4] for i in range(5): xv = [] yv = [] for j, v in enumerate(row[i][1] for row in y_data): if v is not None: xv.append(j) yv.append(v) ax.plot(xv, yv, label=y_data[0][i][0]) Here instead of using a mask like in the linked question/answer, I've explicitly built up the lists of valid data points that are to b

How to distribute a stand-alone python application?
Why don't you create a directory with the interpreter you want to use, add in any modules etc. Then drop in a bash script, say run.sh which calls the program. It can launch your chosen interpretter with your python files, arguments etc. Any source files can remain this way and be edited in place. You could tar and distribute the whole directory, or put in something like git.

Compiling shared library for python to distribute
I've been getting the same error/having the same problem. I'd be interested if you've found a solution. I have found that if I compile against the native python include directory and run the native OS X python binary /usr/bin/python that it works just fine, always. Even when I compile against some other python library (like the one I find at /Applications/Canopy.app/appdata/canopy-1.0.3.1262.macosx-x86_64/Canopy.app/Contents/include ) I can get the native OS X interpreter to work just fine. I can't seem to get the Enthought version to work, ever. What directory are you compiling against for use with Enthought/Canopy? There also seems to be some question of configuring SWIG at installation to know about a particular python library, but this might not be related: http://swig.10945.n7.nabb

Algorithm for Finding a circle among 2n+3 points such that it contains n points inside, n points outside and 3 points on itself
You could consider using a QuadTree: Quadtree on wiki Then using this structure you could scan the proximity of each node. There seems to be a function called Query Range. This function will allow you to be more precise than just exhaustively picking circles I think. Note this is not the solution, just an idea to get you started.

converting python program into executable
If you want to make it executable, you have to chmod +x /path/to/script.py. This gives anybody permission to run the file. Then you can python /path/to/script.py. You still need to start the command with python, that is ugly. If you add this line #!/usr/bin/env python to the first line of your script. This is callled a shebang or a hashbang. Then (still remember to chmod it) you can /path/to/script.py and it will execute. If you are already in the directory of your script you can ./script.py. (still remember to chmod it and at a shebang) If you still aren't satisfied, and you want to type in just the name of your script, you move the script into one of the folders on your path (which you can find by typing echo $PATH in shell, typically this is /usr/, /bin/, /usr/local/bin, or something

How do I make Python script executable?
One thing I am pretty sure you can do, though it's fragile and is not that suitable for deploying across multiple users, is make a shortcut to your Python.exe binary and edit the shortcut command line to be something like: "C:Python31python.exe" <path to your script> The main problem with this, and the reason it's not very desirable, is that each copy needs to be modified if the paths change. Another possibility is to wrap the Python script's execution in a .bat file. Shashank Gupta, in comments above, also recommends checking out cxfreeze. I haven't used this tool, but it might work for you.

Identify directories that are packages in Mac OS X with Python
OS X packages (and bundles) are usually defined by their extension. Simply create a directory with an .app extension to see it be presented as a (broken) application in the Finder. The official documentation lists the following ways to define bundles: The Finder considers a directory to be a package if any of the following conditions are true: The directory has a known filename extension: .app, .bundle, .framework, .plugin, .kext, and so on. The directory has an extension that some other application claims represents a package type; see “Document Packages.” The directory has its package bit set. The preferred way to specify a package is to give the package directory a known filename extension. For the most part, Xcode takes care of this for you by providing tem

How to make a Python script an executable program
If you just need to make the python programs executable, then you can add a line to the top like this: #!/usr/bin/python Replace /usr/bin/python with the filepath to python, which can be obtained by typing which python into the terminal, assuming you're using a unix-based system. You can then tell the operating system that the program is executable with chmod +x nameofprogram If the java programs require something more complicated than just being able to run the python parts as executables, then you'll probably need to provide more information for anyone to be able to help you.

python how to build an executable with ffmpeg and lame
See this wikipedia List of installation software. I have used Install4j (costs $2K) and IzPack (free); both require the JVM, and a few days each of testing and experimentation. There are other options that don't appear to require JVM. While your current target is OSX, if you are considering multi-platform it is well worth testing on Linux and Windows from the start. How to go about it? Build up a sample installation, then use the tool to bundle it up and install on the target machine. And test, test, test. Spend some time thinking about what kind of future change you want to support (that's where the multi platform bit helps), and what minimum OS version and machine config you require. Finally: make sure you are complying with the licenses of both ffmpeg and lame, and the tool you us

How to turn Python program into executable file
Here are a few options: Platypus is not Python-specific. It lets you wrap a simple GUI around a command line tool. py2app is Python-specific and a good choice if you have a GUI, or need to run in the background. PyInstaller is similar to py2app but cross-platform; I've never used it, so I don't know how well it works. The right choice depends on what your program does; who is the expected audience — do you need to redistribute it, if so how, and so forth. If you want to make the application entirely self-contained — not dependent on anything else beyond the OS — then things get more complicated (though certainly not insoluble; there are several commercial Mac desktop apps written in Python.)

Python: I can't import a module even though it's in site-packages

Simply do: python setup.py install And the module will be installed correctly in the site-packages of the python interpreter you are using. If you want to install it for a specific python version use python2/python3 instead of python.
