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

pip install pyiter

Quickstart

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()
