5 Python tricks boost code

Short summary

Master five practical Python optimization techniques: list comprehensions are 2x faster than loops, enumerate/zip simplify iteration, context managers prevent resource leaks, match-case replaces verbose conditionals, and __slots__ reduces per-instance memory by 40-60%. All immediately applicable for cleaner, more efficient code.

• •List comprehensions run 2x faster than traditional for-loop append patterns
• •enumerate() and zip() provide cleaner syntax for indexed and paired iteration
• •match-case pattern matching (Python 3.10+) replaces verbose if-isinstance chains
