In this lesson, the code under section " Adding a helper function to merge tokens" is missing to append the last_token variable to merged_tokens list (in fact reassign new value for the last token of the list).

I believe that part of code shalle be ,

last_token = merged_tokens[-1]
last_token['word'] += token['word'].replace('##', '')
last_token['end'] = token['end']
last_token['score'] = (last_token['score'] + token['score']) / 2
# Missing code
merged_tokens[-1] = last_token

I have made the following changes for better result of mergers

if (merged_tokens and token['word'].startswith('##')) or (merged_tokens and token['entity'].startswith('I-') and merged_tokens[-1]['entity'].endswith(token['entity'][2:])):
            last_token = merged_tokens[-1]
            last_token['word'] += token['word'].replace('##', '')
            last_token['end'] = token['end']
            last_token['score'] = (last_token['score'] + token['score']) / 2
            merged_tokens[-1] = last_token

Hope the above helps.
