Eaterate

Eaterate (eet-uh-rate) is a toolkit of modern Python iterators. Or whatever the hell you wanna call this.

Key features:

• Fully typed. C'mon, type annotations are just essential these days.

from eaterate import eater

eat = eater("hi!").enumerate()

for index, char in eat:
    print(index, char)

# Output:
# 0 h
# 1 i
# 2 !

Quick tour

With eaterate, you can use iterators in the easiest way possible:

eat = (
    eater([1, 2])
    .chain([4, 5])
    .map(lambda i: i * 2)
)

# collects to a list
print(eat.collect(list))

# [2, 4, 8, 10]

You can also add separators to your iterator like never before (kind of):

eat = eater([1, 2, 3]).intersperse(500)
for i in eat:
    print(i)

# Output:
# 1
# 500
# 2
# 500
# 3

There are a lot more features to try out! Refer to the Core API reference for more!

Architecture

Instead of raising StopIteration (exception-like) when an iterator ends, eaterate uses value wrappers, specifically Option[T].
