Nodes

filter
content	filter(function, iterable): Construct an iterator from those elements of iterable for which function is true. iterable may be either a sequence, a container which supports iteration, or an iterator.
children	python/docs/reference/expressions/lambda, map (map/filter pairing)
parents	leetcode/problems/125_valid_palindrome, python/docs/stdlib
hyperlink	https://docs.python.org/3/library/functions.html#filter
location	knowledge/python.dz:95

map
content	map(function, iterable, *iterables): Return an iterator that applies function to every item of iterable, yielding the results. If additional iterables arguments are passed, function must take that many arguments and is applied to the items from all iterables in parallel.

2024-12-23 08:28 Getting my dagzet stuff working with link curation.

All I want to do at the moment is get an argument into my program ala argc/argv in C. The CLI stuff is a bit overkill, but nice to know it's included. sys.argv is what I wanted.
