Welcome to types-linq’s documentation!

types-linq is a lightweight Python library that attempts to implement LINQ (Language Integrated Query) features seen in .NET languages (see here for their documentation).

This library provides similarly expressive and unified querying exprience on objects so long as it is iterable. With few simple method calls and lambdas, developers can perform complex traversal, filter and transformations on any data that typically had to be done with many iterative logics such as for loops.

There have been several libraries that try providing such functionalities, while this library tries to accomplish something different:

• It incorporates the original APIs in .NET IEnumerable class as close as possible, including method names, conventions, edge behaviors, etc. This means typical Python conventions might be shadowed here

• It tries to implement deferred evaluations. The library operates in a streaming manner if possible and handles infinite streams (Python generators) properly

• Strong type safety while using this library is guarenteed since the APIs are typed

• It honours the Python collections.abc interfaces
