This is the readme for the Python for Win32 (pywin32) extensions, which provides access to many of the Windows APIs from Python.
See CHANGES.txt for recent notable changes.
A special shout-out to @xoviat who provided enormous help with the github move!
However, please do not open github issues for general support requests, or for problems or questions using the modules in this package - they will be closed. For such issues, please email the python-win32 mailing list - note that you must be subscribed to the list before posting.
By far the easiest way to use pywin32 is to grab binaries from the most recent release
Installing via PIP
Note that PIP support is experimental.
You can install pywin32 via pip:
pip install pywin32
Note that if you want to use pywin32 for "system wide" features, such as registering COM objects or implementing Windows Services, then you must run the following command from an elevated command prompt:
python Scripts/pywin32_postinstall.py -install
Building from source
Building from source is extremely complicated due to the fact we support building
old versions of Python using old versions of Windows SDKs. If you just want to
build the most recent version, you can probably get away with installing th
same MSVC version used to build that version of Python, grabbing a recent
Windows SDK and running
setup.py is a standard distutils build script. You probably want:
python setup.py install
python setup.py --help
You can run
setup.py without any arguments to see
specific information about dependencies. A vanilla MSVC installation should
be able to build most extensions and list any extensions that could not be
built due to missing libraries - if the build actually fails with your
configuration, please open an issue.
The following steps are performed when making a new release - this is mainly to form a checklist so mhammond doesn't forget what to do :)
Ensure CHANGES.txt has everything worth noting, commit it.
Update setup.py with the new build number.
Execute build.bat, wait forever, test the artifacts.
Commit setup.py (so the new build number is in the repo), create a new git tag
Upload the .exe installers to github, the .whl files to pypi.
Update setup.py with the new build number + ".1" (eg, 123.1), to ensure future test builds aren't mistaken for the real release.
