list

List literals [1, 2, 3], list(iterable), and methods returning lists.

Method	Returns	Meaning
`.length`	number	Item count, same as `len(lst)`. Property: no parens
`.append(item)`	None	Add to the end (raises past the interpreter’s max-length cap)
`.pop(index=-1)`	any	Remove and return (default last); negative indices from the end; empty/out-of-range raises
`.remove(item)`	None	Remove first occurrence by value; raises if absent
`.insert(index, item)`	None	Insert, shifting right; out-of-range indices clamp to the ends (no error)
`.index(item, start=0, end=None)`	number	First occurrence in the slice; raises if not found
`.count(item)`	number	Occurrences (deep value equality for numbers, strings, booleans)
`.sort(key=None, reverse=False)`	None	In-place sort using `<`. `key=` must be pure: it cannot suspend the script or mutate game state
`.reverse()`	None	Reverse in place
`.copy()`	list	Shallow copy
`.extend(iterable)`	None	Append every item from a finite iterable
`.clear()`	None	Remove all items
