Some of the techniques for improving Python code performance include concatenating strings with join, applying multiple assignments, using generators as keys for sorting, interning strings, and using the built-in timeit module. Optimizing Python code for performance involves several strategies to improve efficiency. Start by profiling your code to identify bottlenecks using tools like cProfile or line_profiler. Use efficient data structures such as tuples, sets, and dictionaries. Optimize loops by avoiding unnecessary calculations and using list comprehensions. Leverage built-in functions and libraries like NumPy for performance-critical tasks. Minimize the use of global variables, and prefer local variables for faster access. Use string join() for concatenation. Implement caching with functools.lru_cache and consider JIT compilation with Numba. For I/O-bound tasks, use asynchronous programming with asyncio. Avoid unnecessary object creation and consider using C extensions for critical sections. always aim to balance optimization with code readability and maintainability.
