Generate human-readable representations of numbers of bytes.

Project description

byteformat is a Python library and command line script for displaying numbers of bytes as strings using standards-compliant human-readable units such as ‘23 KB’ or ‘1.25 terabytes’.

  • Supports both official standards and the common de facto standard:

    • SI decimal units, e.g. 1000 bytes = 1 KB;
    • IEC binary units, e.g. 1024 bytes = 1 KiB;
    • Mixed decimal names with binary sizes, e.g. 1024 bytes = 1 KB.
  • Supports the full set of decimal prefixes from kilo- to yotta- and the binary prefixes kibi- to yobi-.

  • Generate strings using symbols (e.g. ‘KB’), abbreviated names (‘Kbyte’) or full names (‘kilobyte’).

  • Uses correct plural terms when needed.

  • Automatically selects the best unit for a given number of bytes.

  • Allows the caller to explicitly override that selection and select which unit to use.

  • Easily customise the output without subclassing.

  • Importable as a Python library module.

  • Runs as a command line script.
