You can check these things for yourself:
will show you the byte code.
But in general, I would expect not. CPython (that's the Python you
probably use) doesn't do a lot of optimization apart from some simple
constant folding. If you're interested in optimizing Python, you should
look at the JIT optimizing Python compiler, PyPy.
