What are the best practices for optimizing Python code for performance?

The question is about Python

Answer:

Optimizations of performance in Python should focus on using proper data structures, reducing global variables, and not recalculating values when those computations have already been made. Typical profiling will involve cProfile. Using built-in functions and libraries – NumPy and just-in-time compilation by using tools like PyPy go a long way toward the performance enhancement.
