Python 2. The zipimport mechanism is able to handle the early imports of the warnings and also the encodings module which is done by Python. Assuming you have written a python script myscript. If you don't already have written a distutils setup-script , write one, and insert the statement import py2exe before the call to the setup function:. If your script uses compiled C extension modules, they will be copied here as well, also all dlls needed at runtime except the system dlls.
These files include everything that is needed for your program, and you should distribute the whole directory contents. Some applications need additional files at runtime, like configuration files, fonts, or bitmaps. Optionally, you can specify a 'cmdline-style' attribute to py2exe, with valid values being 'py2exe' the default , 'pywin32' or 'custom'.
The built service executables are able to install and remove themselves by calling them with certain command line flags, run the exe with the -help argument to find out more. By default py2exe creates these files in the dist directory which you must deploy:. The bundled pyds and dlls are never unpacked to the file system, instead they are transparently loaded at runtime from the bundle.
The resulting executable appears to be statically linked. Specifying a level of 2 includes the. Thus, the dist directory will contain your exe file s , the library. The advantage of this scheme is that the application can still load extension modules from the file system if you extend sys. Using a level of 1 includes the. The advantage is that you only need to distribute one file per exe, which will however be quite large.
Another advantage is that inproc COM servers will run completely isolated from other Python interpreters in the same exe. The disadvantage of this scheme is that it is impossible to load other extensions from the file system, the application will crash with a fatal Python error if you try this. I have still to find a way to prevent this and raise an ImportError instead - any suggestions how this can be implemented would be very welcome.
The bundle-option has been tested with some popular extensions, but of course there's no guarantee that any extension will work in bundled form - be sure to test the executable which you should do anyway.
The bundle option achieves its magic by code which emulates the Windows LoadLibrary api, it is compiled into the exe-stubs that py2exe uses. The Python module zipextimported. The singlefile subdirectory contains two samples which are built as single-file executables: a trivial wxPython gui program, and a pywin32 dll COM server module. Pure python modules are compiled into. Compiled extension modules. A zip-compatible archive is built, containing all python files from this directory.
