28. Extract Phone Numbers from Column

Write a Pandas program to extract only phone number from the specified column of a given DataFrame.

Sample Solution:

Python Code :

import pandas as pd
import re as re
pd.set_option('display.max_columns', 10)
df = pd.DataFrame({
    'company_code': ['c0001','c0002','c0003', 'c0003', 'c0004'],
    'company_phone_no': ['Company1-Phone no. 4695168357','Company2-Phone no. 8088729013','Company3-Phone no. 6204658086', 'Company4-Phone no. 5159530096', 'Company5-Phone no. 9037952371']
    })
print("Original DataFrame:")
print(df)
def find_phone_number(text):
    ph_no = re.findall(r"\b\d{10}\b",text)
    return "".join(ph_no)
df['number']=df['company_phone_no'].apply(lambda x: find_phone_number(x))
print("\Extracting numbers from dataframe columns:")
print(df)

Sample Output:

Original DataFrame:
  company_code               company_phone_no
0        c0001  Company1-Phone no. 4695168357
1        c0002  Company2-Phone no. 8088729013
2        c0003  Company3-Phone no. 6204658086
3        c0003  Company4-Phone no. 5159530096
4        c0004  Company5-Phone no. 9037952371
\Extracting numbers from dataframe columns:
  company_code               company_phone_no      number
0        c0001  Company1-Phone no. 4695168357  4695168357
1        c0002  Company2-Phone no. 8088729013  8088729013
2        c0003  Company3-Phone no. 6204658086  6204658086
3        c0003  Company4-Phone no. 5159530096  5159530096
4        c0004  Company5-Phone no. 9037952371  9037952371
