Koan 10: The Flowing River (Part 1) open.substack.com / https://open.substack.com/pub/pythonkoans/p/koan-10-the-flowing-river-part-1?utm_source=share&utm_medium=android&r=5yt43c Understanding how Python's list comprehensions work under the hoodVibecoding “floods the zone” for the developer. They get absolutely inundated with chat output as well as code diffs. No matter how much you “review” you’re never going to understand the code as much as if you had written it yourself.
One thing I detest about AI generated Python code is the ungodly amount of private helpers to do basic shit: def _strip_whitespace def _get_first_element Just stop.

Koan 4: The Grand Library pythonkoans.substack.com / https://pythonkoans.substack.com/p/koan-4-the-grand-library Understanding Python’s LEGB rule, closures, and how names echo through nested functions#python sets are useful when you need: - fast membership testing - deduplication or uniqueness guarantees - comparing two sets of items
#python list tips: - reversed(list) is more memory efficient for reversing a list than slicing list[::-1] because it returns an iterator instead of a copy - You can remove multiple items with slice assignment using list[1:4] = [] or del a[1:4]
#python variable scoping can be confusing if you’re used to other programming languages. A scope determines where a variable name is visible, and it’s lifetime. Python checks for the variable definition in the following order, and stops at the first match
