# Python overview
## About The `Python` API is provided by the file [gsapi.py] - this is the binding to the Ghostscript `C` library. In the [GhostPDL repository] sample `Python` examples can be found in `/demos/python/examples.py`. ## Platform & setup ### Building Ghostscript Ghostscript should be built as a shared library for your platform. See [Building Ghostscript]. ## Specifying the Ghostscript shared library Two environmental variables can be used to specify where to find the Ghostscript shared library. `GSAPI_LIB` sets the exact path of the Ghostscript shared library, otherwise, `GSAPI_LIBDIR` sets the directory containing the Ghostscript shared library. If neither is defined we will use the OS's default location(s) for shared libraries. If `GSAPI_LIB` is not defined, the leafname of the shared library is inferred from the OS type - `libgs.so` on Unix, `libgs.dylib` on MacOS, `gsdll64.dll` on Windows 64. ## API test The `gsapi.py` file that provides the `Python` bindings can also be used to test the bindings, by running it directly. Assuming that your Ghostscript library has successfully been created, then from the root of your `ghostpdl` checkout run: #### Windows
