32. Memory Optimization

Python provides tools and patterns to reduce memory usage.

Techniques​

  • Use generators instead of lists for large data
  • Use __slots__ to save memory in classes
  • Delete unnecessary references with del

Example​

def read_large_file(filename):
    with open(filename) as f:
        for line in f:
            yield line

Wrap-Up​

Memory optimization is critical for scaling applications.
