Excel File

I would like to cut county Norfolk and paste it to new column 'County'

Answer 1

You could do it in two steps

1. Copy Over 'Norfolk', if column string has 'Norfolk' substring

2. Strip original column.

    def copy(row): if 'Norfolk' in row[col_index_in_question]: return 'Norfolk' def strip(row): return row[col_index_in_question].replace('Norfolk', '') df['County'] = df.apply(copy, axis=1) df[col_index_in_question] = df.apply(strip, axis=1) 

Replace col_index_in_question with you column index

But more importantly if it's a specific formatted address that you want to parse, you can use this Python Parser Lib
