Only JRE. Just like Java.

.pyc files are generated every time a module (any .py file can be a 
module) is imported. So if you have a program, say, example.py, you 
just start the python interpreter and write:
>>> import example
And then example.pyc will appear beside example.py. This new file does 
not require example.py (you can even delete it), and works on any 
computer with Python installed (on Windows you can just double-click 
it)
If you start the Python interpreter using:
python -OO (if you are using Windows, you shoud start the interpreter 
from the command line, probably something like:
c:
cd \
python24\python -OO)
and then import your example.py, you will get a file example.pyo, 
which is also stripped of any documentation strings (a bit harder to 
decode).
