Calculate entropy
Project description
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.
