iterable-io
Adapt generators and other iterables to a file-like interface
Decision gist · record as of 2026-08-14
Yes. The package solves a real interface-adaptation problem with zero dependencies, low install friction, active maintenance, and no known vulnerabilities. The copyleft license (LGPL-3.0-only) is straightforward for most use cases but requires review if you plan to modify or redistribute the code. Install it when you need to feed an iterable into code expecting a file-like object.AI-flagged interpretation of the facts on this page — verify before relying
Before you install
- No runtime dependencies and a pure-Python wheel distribution make installation straightforward.
- The package is actively maintained with a recent release.

What it is and what it does
iterable-io bridges a common interface mismatch: when one part of your code has a generator or other iterable producing data, but another part expects a file-like object with a `.read()` method. Rather than materializing the entire iterable into a temporary file (which is slow and memory-intensive), this library streams data on demand, pulling from the iterable as `.read()` is called.
The package exports a single function, `open_iterable()`, designed to mimic Python's builtin `open()`. It accepts an iterable, a mode string ('rb', 'rt', etc.), and optional parameters like encoding and buffering, returning a file-like object. This is useful for gluing together incompatible APIs—for example, when a library expects a file handle but your data comes from a generator of bytes or lines.
Use it for
- Adapt a generator of bytes to feed into a library that requires a file-like object (e.g., image processing, archive extraction).
- Stream text data line-by-line from a generator without materializing the full dataset into memory.
- Convert network streams or database result iterators into file-like interfaces for downstream processing.
- Avoid temporary file creation when bridging APIs that produce and consume data differently.
- Read compressed or encoded data from a generator while handling text-mode decoding transparently.
