These functions are written in C. You can view the source code here (be sure to select the correct version by tag) or download the source tarball from here.
Anyway, you can find the code for all function in
__builtin__in the filePython/bltinmodule.c. I.e. the implementation offilteris a function calledbuiltin_filter.The sources for other modules are in the
Modules/folder.
