Map takes a function and a collection of items. It makes a new, empty collection, runs the function on each item in the original collection and inserts each return value into the new collection. It returns the new collection.
This is a simple map that takes a list of names and returns a list of the...
Reduce takes a function and a collection of items. It returns a value that is created by combining the items.
This is a simple reduce. It returns the sum of all the items in the collection.
total = reduce(lambda a, x: a + x, [0, 1, 2, 3, 4])
print(total) =>10
Filter takes a function and a collection. It returns a collection of every item for which the function returned True.
