Single-File Stand-alone Python 2.7.9 for Windows

The program has moved to GitHub. Newer builds and changes are there.

Download

py.exe - Python 2.7.9 as a single, stand-alone executable with virtually all the standard libraries, plus pywin32-219 and psutil 2.1.3. Compiled with py2exe (see source below) on Windows XP. This should work on Windows XP and later. This works just like a full install of python, except you only need the one file. 9.9 Mb.

pyexe-2.7.9.10.zip - Zip file of the stand-alone exectuable. 9.8 Mb.

pyexe-src-2.7.9.10.zip - The source code for making the py.exe file. See the README.TXT within the zip file for details. Requires a full install Python 2.7.9, pywin32-219, psutil 2.1.3, setuptools.py, and py2exe. 10 kb.

Rationale

I frequently write programs in python as it is a handy, powerful language. However, sometimes I don't want to install it. There are some other projects to give a portable python implementation. That still seems too heavy for some tasks.

Here is a Windows executable form of Python 2.7.9 that contains most of the standard libraries, plus pywin32. It has the following features:

• Single file with no dependencies besides Windows (XP or later)
• Can run python programs (e.g., py.exe sample_program.py)
• Can be used as an interactive shell (e.g., py.exe, then start typing)
• Can be used to execute string commands (e.g., py.exe -c "print 'hello world'")

I've included the very simple source code, which is nothing more than a setup.py script using py2exe. I compressed the executable using upx, which reduces its size by 12% or so and doesn't substantially slow down starting the program.

Note: I have one report that when running the program on Windows 7 64-bit, you need to have the current working directory set to the location of the py.exe program. Not having a copy of Windows 7 64 bit, I cannot determine if I could work around this issue.

Change Log

See the program source for the definitive change log.

2.7.9.11:

Moved to GitHub and now built for Python 2.7, 3.5, and 3.6.

2.7.9.10:

Upgraded to python 2.7.9
Added psutil 2.1.3 win32
Added support for the -m option.
Turned off the optimization flag when building py.exe. Having it on interferes with some modules (such as sympy) which rely on docstring manipulation.

2.7.8.9:

• My change to make globals dictionaries more consistent broke multiprocessing forking. I've reverted some of the changes.

2.7.8.8:

• Fixed a bug I introduced in the last version when renaming the variable "loc".

2.7.8.7:

• Added support for -E, -x, and --version options.
• Changed how the globals / locals dictionaries are used for greater consistency in different execution modes.
• Accept multiple single letter command line options grouped together.

2.7.8.6:

• Added support for multiprocessing forking
• Added support for non-ttty direct usage (input and output pipes, for instance)
• Added support for -i option and PYTHONINSPECT environment variable.
• Turned off "frozen" flag in py.exe
• Upgraded pywin32 to build 219 (was 218).
• Upgraded to python 2.7.8
• Added import site to interactive prompts to get help and other commands added to the builtins.
• Added support for unbuffered -u option and PYTHONUNBUFFERED environment variable.

2.7.5.5:

• Imported submodules, such as logging.handlers, since they weren't included implicitly.

2.7.5.4:

• Upgraded to python 2.7.5

2.7.4.3:

• Added the program path to sys.path when running a program, and "" to sys.path when running direct or interpretted.

2.7.4.2:

• fixed an issue with __file__ and __name__

2.7.4.1:

• initial release
