9 Python Performance Optimization Techniques for Faster Code
Faster Loops: Prioritize Local Variables
In Python, accessing local variables is faster than accessing global variables or object attributes.
import timeit
class DataProcessor:
def __init__(self):
self.counter = 0
def test_attribute_access():
processor = DataProcessor()
for _ in range(1000):
processor.counter + ...

Exploring AST Optimization Techniques in CPython's Compiler Pipeline
Beyond constant folding, CPython's abstract syntax tree (AST) optimizer implements several other transformations that reduce runtime work. These optimizations are applied during compilation, converting high-level constructs into simpler constant forms or more efficient bytecode sequences. Below we examine the key internal functions that drive t ...
