iters

Composable external iteration.

If you have found yourself with a collection of some kind, and needed to perform an operation on the elements of said collection, you will quickly run into iterators. Iterators are heavily used in idiomatic Python code, so becoming familiar with them is essential.

Installing

Python 3.8 or above is required.

pip

Installing the library with pip is quite simple:

$ pip install iters

Alternatively, the library can be installed from source:

$ git clone https://github.com/nekitdev/iters.git
$ cd iters
$ python -m pip install .

poetry

You can add iters as a dependency with the following command:

$ poetry add iters

Or by directly specifying it in the configuration like so:

[tool.poetry.dependencies]
iters = "^0.18.0"

Alternatively, you can add it directly from the source:

[tool.poetry.dependencies.iters]
git = "https://github.com/nekitdev/iters.git"

Examples

Simple

Squaring only even numbers in some sequence:

from iters import iter


def is_even(value: int) -> bool:
    return not value % 2


def square(value: int) -> int:
    return value * value


numbers = [0, 1, 2, 3, 4, 5, 6, 7, 8, 9]

result = iter(numbers).filter(is_even).map(square).list()

print(result)  # [0, 4, 16, 36, 64]

Asynchronous

Asynchronous iteration is fully supported by iters, and its API is similar to its synchronous counterpart.
