2  109986            


        

Answer 1

This answer can also be used - Count distinct words from a Pandas Data Frame. It utilizes the Counter method and applies it to each row.

from collections import Counter
c = Counter()
df = pd.DataFrame(
    [[104472,"R.X. Yah & Co"],
    [104873,"Big Building Society"],
    [109986,"St James's Society"],
    [114058,"The Kensington Society Ltd"],
    [113438,"MMV Oil Associates Ltd"]
], columns=["URN","Firm_Name"])
df.Firm_Name.str.split().apply(c.update)

Counter({'R.X.': 1,
         'Yah': 1,
         '&': 1,
         'Co': 1,
         'Big': 1,
         'Building': 1,
         'Society': 3,
         'St': 1,
         "James's": 1,
         'The': 1,
         'Kensington': 1,
         'Ltd': 2,
         'MMV': 1,
         'Oil': 1,
         'Associates': 1})
