Functionality that should be in the standard library

Boltons is a set of over 230 BSD-licensed, 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
