A minimal build of python was included as a dependency of gdb in
Rtools 3.3 and up.

Please don't assume but read the documentation (preferably before posting).

We have a dual toolchain so there is a 32 and a 64 bit build of
python2.7.exe. The other names (python.exe and python2.exe) are
symlinks that python automatically creates. These are not in any
location that is ever on the path so nothing to worry about.
