# PyIter

[![Pypi version](https://img.shields.io/pypi/v/pyiter?style=for-the-badge)](https://pypi.org/project/pyiter/)

PyIter is a Python package for iterative operations inspired by the Kotlin、CSharp(linq)、TypeSrcipt and Rust .

Enables strong **typing** and type inference for iterative operations.

- Chain operations like map, reduce, filter, map

- Lazy evaluation

- parallel execution

- strong **typing**

## Install

```bash

pip install pyiter

```

## Quickstart

```python

from pyiter import it

from tqdm import tqdm

text = ["hello", "world"]

it(text).map(str.upper).to_list()

# ['HELLO', 'WORLD']

words = 'I dont want to believe I want to know'.split()

it(words).group_by(lambda x: x).map(lambda g: (g.key, g.values.count())).to_list()

# [('I', 2), ('dont', 1), ('want', 2), ('to', 2), ('believe', 1), ('know', 1)]

# use tqdm

it(range(10)).map(lambda x: str(x)).progress(lambda x: tqdm(x, total=x.len)).parallel_map(lambda x: x, max_workers=5).to_list()

```

**Type inference**
