IN PYTHON

Here is the input for the Byte Pair Encoding (BPE) algorithm: "Baker Betty Lou bought some butter. But, it made her batter bitter. So, Baker Betty Lou bought some better butter to make her bitter batter better." You can either implement BPE in Python or use the pseudo code (from the textbook or the slides) and hand calculate the output. Run the BPE algorithm at least 7 times. That is k should be 7 or more. Upload your code with output (Jupyter notebook is welcome) or your detailed hand calculations. Show the initial vocabulary and the vocabulary after each iteration. Show, proof that vocabulary addition is justified at each iteration.
