Answer 1

Input

inp = [{'file_path': '/home', 'header': 'hi', 'id': '12', 'description': ' It contain some value ', 'file_name': 'sile.xls'}, {'file_path': '/home', 'header': 'hello', 'id': '34', 'description': 'it has value', 'file_name': 's.docs'}]

Code

res={}
for i in inp:
   k = i['description'].split()
   for n in k:
      if not n in res:
            res[n]=1
      else:
            res[n] +=1
print(res)

Output

{'some': 1, 'it': 1, 'value': 2, 'It': 1, 'contain': 1, 'has': 1}
