By using only coding patterns that are known to JIT well and lower level primitive types and containers if provided by the language. Maximizing the use of packages written in native code also helps. The resulting code is even more annoying to write than using a lower level language typed language in the first place, but ecosystem access sometimes makes up for it. Hopefully tools like mypyc get better, letting well-typed python code with reasonable usage patterns be compiled to reasonably efficient native code. Last time I used it I was pleased with the performance benefits but it couldn't even compile all files in a module to a single shared library, despite this being mentioned as possible (and recommended) in the docs. Maybe I was doing something wrong, but they don't answer their github issues often, alas. Any little thing helps though, it's one thing for throwaway scripts to be inefficient, but applications? At a large scale it is a monstrous waste of time and literal energy.
