The “wheel” library aims to provide basic (and some not-that-basic) facilities that one would expect to have in C. For the moment it contains:

• Memory handling routines.
• In-memory buffers.
• Support for loading and saving “configuration” files. Actually, This
  module can be (ab)used to save and load arbitrary data.
• Hash-based dictionaries (being dictionaries means that keys are always
  strings).
• String handling functions.
• Command line parsing.
• Utilities for building simple parsers.
• Generic input/output streams.
