Answer:

  • Use NumPy, Pandas, or Cython for heavy computations.
  • Use multiprocessing or asyncio for parallelism.
  • Cache results via functools.lru_cache.
  • Use PyPy or Just-In-Time (JIT) compilers.
  • Profile code using cProfile or line_profiler.

Example:

from functools import lru_cache

@lru_cache(maxsize=None)
def fibonacci(n):
    if n < 2:
        return n
    return fibonacci(n-1) + fibonacci(n-2)
