"WebbI also wrote Huffman coding in Python using bitarray for more background information. When the codes are large, and you have many decode calls, most time will be spent creating the (same) internal decode tree objects. In this case, it will be much faster to create a decodetree object, which can be passed to bitarray's .decode() and .iterdecode ... " - In huffman coding method
