<p style="color: grey"> Python recipe 577502 by <a href="/recipes/users/4172570/">FB36</a> (<a href="/recipes/tags/algorithm/">algorithm</a>, <a href="/recipes/tags/algorithms/">algorithms</a>, <a href="/recipes/tags/data_compression/">data_compression</a>). Revision 3. </p> <p>Shannon-Fano Data Compression. It can compress any kind of file up to 4 GB.</p> <p>(But trying to compress an already compressed file like zip, jpg etc. can produce a (slightly) larger file though. Shannon-Fano is not the best data compression algorithm anyway.)</p>
