py2exe is a distutils extension which allows to build standalone Windows executable programs (32-bit and 64-bit) from Python scripts; Python 3.3 and later are supported. It can build console executables, windows (GUI) executables, windows services, and DLL/EXE COM servers.
py2exe for Python 2 is still available at http://sourceforge.net/project/showfiles.php?group_id=15583.

Version 0.9.2.2: Added support for six, cffi, pycparser, openssl. Support cmdline_style ("py2exe", "pywin32", "custom") again for windows services. Several bugfixes, better error messages.
The C-runtime library for Python 3 does NOT need a windows manifest any longer to load correctly (this is a feature of Python, not of py2exe).
py2exe now contains a hooks module which contains information about some standard packages. The goal is to fine-tune the build process so that no (at least less) warnings are emitted from modulefinder.
Thanks to a brand new modulefinder (based on Python's importlib) py2exe can now find and extract modules even from packages you have installed as zipped eggs.
py2exe now longer uses a build directory for temporary files.
It is planned to achive full compatibility with the setup-scripts for Python 2; however this is probably not yet the case.
In addition to your beloved setup.py scripts :-), there is now also a command-line utility which allows to build the exe without any effort.
Running
py -3.4 -m py2exe.build_exe myscript.py
or (if you have the Python Scripts
directory on your PATH):
build_exe myscript.py
will create an executable myscript.exe in the dist subdirectory.
If you add the -W <setup-script.py>
switch to the above command
line a commented setup.py
script will be generated which can be
used to further customize the exe:
py -3.4 -m py2exe myscript.py -W mysetup.py ... edit myssetup.py py -3.4 mysetup.py py2exe
py -3.4 -m pip install py2exe
or
pip install py2exe
Build runtime archive for a script:
build_exe [-h] [-i modname] [-x modname] [-p package_name] [-O] [-s] [-r] [-f modname] [-v] [-c] [-d DESTDIR] [-l LIBNAME] [-b {0,1,2,3}] [-W setup_path] [-svc service] [script [script ...]]
- positional arguments:
- script
- optional arguments:
-h, --help show this help message and exit -i modname, --include modname module to include -x modname, --exclude modname module to exclude -p package_name, --package package_name module to exclude -O, --optimize use optimized bytecode -s, --summary print a single line listing how many modules were found and how many modules are missing -r, --report print a detailed report listing all found modules, the missing modules, and which module imported them. -f modname, --from modname print where the module <modname> is imported. -v verbose output -c, --compress create a compressed library -d DESTDIR, --dest DESTDIR destination directory -l LIBNAME, --library LIBNAME relative pathname of the python archive -b option, --bundle-files option - How to bundle the files:
- 3 - create script.exe, python.dll, extensions.pyd, others.dll. 2 - create script.exe, python.dll, others.dll. 1 - create script.exe, others.dll. 0 - create script.exe.
-W setup_path, --write-setup-script setup_path Do not build the executables; instead write a setup script that allows further customizations of the build process. - -svc svnmodule, --service svcmodule
- The name of a module that contains a service
Creating an executable (or more than one at the same time) with a setup-script works in the same way as for Python 2. The command-line switches are the same as before; but they are NOT compatible with the command-line switches for the builder mentioned above.
Documentation about the setup-script and other usage tips are in the wiki pages at http://www.py2exe.org.
The applications that py2exe creates will always need the following parts:
- The exe-file(s) itself. py2exe can build several executables at the same time; this is especially useful if these are related to each other since some parts can be shared.
- The python-dll.
- The pure python modules needed to run the app. The byte-code for these modules is always packed into a zip-archive.
- Compiled python-extension modules.
- Supporting dlls, if any.
The bundle-files option determines how these files are packed together
for your application. This is explained with a script test_sqlite.py
that simply contains this code:
import sqlite3 print(sqlite3)
The command to build the exe-file is:
py2exe.build_exe test_sqlite.py -c --bundle-files <option>
The -c
option specifies to create a compressed zip-archive.
--bundle-files 3
is the simplest way. These files will be
created in a dist
subdirectory, about 8 MB total size:
test_sqlite.exe _bz2.pyd _ctypes.pyd _hashlib.pyd _lzma.pyd _socket.pyd _sqlite3.pyd _ssl.pyd _win32sysloader.pyd pyexpat.pyd python34.dll pywintypes34.dll select.pyd sqlite3.dll unicodedata.pyd win32api.pyd win32evtlog.pyd
The zip-archive is appended to the test_sqlite.exe file itself, which has a size of 1.5 MB in this case.
--bundle-files 2
will include all the Python extensions into the
appended zip-archive; they are loaded via special code at runtime
without being unpacked to the file-system. The files in the
dist
directory now are these:
test_sqlite.exe python34.dll sqlite3.dll
--bundle-files 1
will additionally pack the python-dll into the
zip-archive:
test_sqlite.exe sqlite3.dll
--bundle-files 0
now finally creates a real single-file executable
of 6 MB:
test_sqlite.exe
If you are building several related executables that you plan to
distribute together, it may make sense to specify a zip-archive shared
by all the exes with the --library libname
option. The
executables will then become quite small (about 25 kB), since nearly
all code will be in the separate shared archive.
Note that not all applications will work with ``bundle-files`` set to 0 or 1. Be sure to test them.
Building isapi extensions is not supported: I don't use them so I will not implement this.
The modulefinder does not yet support PEP420 implicit namespace packages.
