Calculate entropy

Entropy

Calculate the information entropy of a string, file, etc.

Installation

Install with pip

Usage

Command Line

Basic usage: entropy [-h] [-f FILE | -t TEXT | -p] [-b BASE] [-s] [-m].

Requires one of --shannon (to calculate the Shannon entropy) or --metric (to calculate the Shannon entropy normalised by input size).

Takes input fdom stdin by default, but can read from a file with --file or from the --text argument.

Entropy is calculated in base 2 by default, but this can be changed with --base.

See --help for extended command line usage.

Module

Importing provides an Entropy class which takes bytes and a base (both optional) and exposes methods shannon and metric to calculate the Shannon and normalised entropy. The data can be updated with the update method.
