6 years ago I tried this. But when I do "import mapnik" I get errors:
c:\mapnik-sdk\python\2.7\site-packages\mapnik__init__.py::74 RunTimeWarning: to-Python converter for class std::shared_ptr<struct mapnik::geometry::geometry
I get the same error five times.
I solved this problem by running "del mapnik" before "import mapnik" to remove the 2.2 version.
The demo works!

Since I didn't find any guide, I tried it myself, without knowing whether it will work. It took me more than 1 full day reading repositories, searching binaries, dealing with errors, tracing dll's, jumping through paths. Now I try to condense that down to a few lines. Since I am not a programmer, I understand only partially whats written here. So may be somebody with more insight could check my writings.
Install Visual C++ Redistributable for Visual Studio 2015 x86
Install latest Python 2.7 32-bit, don't try 64-bit. See mapnik/python-mapnik#145
Get https://mapnik.s3.amazonaws.com/dist/dev/mapnik-win-sdk-v3.0.11-x86-14.0.7z There is no download page for the windows binaries. You can also get other versions by changing manually the version number in the link, but unfortunately its not possible to use later releases because of missing python dependencies due to a compiler bug #92
unzip to
C:\prog\mapnik-v3.0.11or whatever you want, but its safer when your path doesn't contain spaces.delete 'include' path, it contains 12000 useless files
check
C:\prog\mapnik-v3.0.11\python\2.7\site-packages\mapnik\_mapnik.pydmust be there. These are the python dependencies.In

C:\Windows\System32\cmd.exe /k C:\prog\mapnik-v3.0.11\set-env-vars.batwith working directoryC:\prog\mapnik-v3.0.11\demo\pythonClicking on it you can start the console with an mapnik 3 working environment which at first checks whether everything is fine.
When you now check out one of the examples styling a map via python code made for mapnik 2, you might encounter some errors, because the polygonsymbolizers, linesymbolizers or textsymbolizers don't work properly in mapnik 3. See mapnik/python-mapnik#7. Recommended way to load a style is to use xml stylesheets instead.
Good luck
EDIT 02.Okt.2017 Now after a while this refused to work. It turned out that the redistributable files for Visual Studio 2015 are no longer correct (vcruntime140.dll and 2 others). Virustotal said they are for ARM architecture :-/ So its good to have a quick check whether it works as I described above. I could solve the problem by uninstalling the Redistributable and installing it again ( repairing didn't work ). Dependency Walker is a good research tool. Just to have a clue whats going on: after typing "import mapnik" in python the following happens:
