The demand for compiled Python hasn't been as high as the demand for other languages, so the number of people who have worked on it is much smaller than the number who have built JITs for ECMAScript and others. Python has long been fast enough for many things, and where it isn't, it's easy to call C code from CPython.
Python does have lesser-used dynamic capabilities that probably don't exist in Common Lisp. Those capabilities make it difficult to optimize arbitrary valid Python code, but most people who need a Python compiler would be happy to make adjustments.
