Pandas: Extract only words from a given column of a given DataFrame

Pandas: String and Regular Expression Exercise-37 with Solution

Write a Pandas program to extract only words from a given column of a given DataFrame.

Sample Solution:

Python Code :

import pandas as pd
import re as re
df = pd.DataFrame({
    'company_code': ['Abcd','EFGF', 'zefsalf', 'sdfslew', 'zekfsdf'],
    'date_of_sale': ['12/05/2002','16/02/1999','05/09/1998','12/02/2022','15/09/1997'],
    'address': ['9910 Surrey Ave.','92 N. Bishop Ave.','9910 Golden Star Ave.', '102 Dunbar St.', '17 West Livingston Court']
})
print("Original DataFrame:")
print(df)

def search_words(text):
    result = re.findall(r'\b[^\d\W]+\b', text)
    return " ".join(result)

df['only_words']=df['address'].apply(lambda x : search_words(x))
print("\nOnly words:")
print(df)

Sample Output:

Original DataFrame:
  company_code date_of_sale                   address
0         Abcd   12/05/2002          9910 Surrey Ave.
1         EFGF   16/02/1999         92 N. Bishop Ave.
2      zefsalf   05/09/1998     9910 Golden Star Ave.
3      sdfslew   12/02/2022            102 Dunbar St.
4      zekfsdf   15/09/1997  17 West Livingston Court

Only words:
  company_code          ...                       only_words
0         Abcd          ...                       Surrey Ave
1         EFGF          ...                     N Bishop Ave
2      zefsalf          ...                  Golden Star Ave
3      sdfslew          ...                        Dunbar St
4      zekfsdf          ...            West Livingston Court

[5 rows x 4 columns]
