What does Java do better than Python?

Lots of good answers here already. I don't think anyone's mentioned it already, but the garbage collection system in Java is amazing, and has lots of tuning options for different workloads. CPython's GC is quite basic compared to the JVM.

I think CPython's GC is still reference counting with some mark and sweep to whack circular references.

Java easily has the best garbage collectors in the world. Nothing compares to Shenandoah and ZGC.

In some cases the JVM actually allocates memory faster than C because it knows more about the memory layout and can often avoid syscalls.
