Is there a way to change this dictionary output?

Change my dictionary, this is the initial code:

bow=[[i for i in all_docs[j] if i not in stopwords] for j in range(n_docs)]
bow=list(filter(None,bow))
bow

Here is bow output:

[['lunar',
  'satellite',
  'needs'],
['glad',
  'see',
  'griffin'] ]

worddict_two = [ (i,key) for i,key in enumerate(bow)]
worddict_two

From this output :

 [(0,
  ['lunar',
   'satellite',
   'needs']),
  (1,
  ['glad',
   'see',
   'griffin'])

to this output:

 [(0,'lunar satellite needs'),
  (1,'glad see griffin') ) ]

>Solution :

worddict_two = [ (i, " ".join(key)) for i,key in enumerate(bow)]

This would work. Use join to Join all items in a tuple into a string with space space as a separator
