python-boltons 20.0.0 Extensions to the Python standard library

Boltons is a set of over 230 pure-Python utilities in the same spirit as — and yet conspicuously missing from — the standard library, including:

  • Atomic file saving, bolted on with fileutils

  • A highly-optimized OrderedMultiDict, in dictutils

  • Two types of PriorityQueue, in queueutils

  • Chunked and windowed iteration, in iterutils

  • Recursive data structure iteration and merging, with iterutils.remap

  • Exponential backoff functionality, including jitter, through iterutils.backoff

  • A full-featured TracebackInfo type, for representing stack traces, in tbutils
