Pandas: Extract words starting with capital words from a given column of a given DataFrame
Pandas: String and Regular Expression Exercise-40 with Solution
Write a Pandas program to extract words starting with capital 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 Avenue','92 N. Bishop Avenue','9910 Golden Star Avenue', '102 Dunbar St.', '17 West Livingston Court']
})
print("Original DataFrame:")
print(df)
def find_capital_word(str1):
result = re.findall(r'\b[A-Z]\w+', str1)
return result
df['caps_word_in']=df['address'].apply(lambda cw : find_capital_word(cw))
print("\nExtract words starting with capital words from the sentences':")
print(df)
Sample Output:
Original DataFrame: company_code date_of_sale address 0 Abcd 12/05/2002 9910 Surrey Avenue 1 EFGF 16/02/1999 92 N. Bishop Avenue 2 zefsalf 05/09/1998 9910 Golden Star Avenue 3 sdfslew 12/02/2022 102 Dunbar St. 4 zekfsdf 15/09/1997 17 West Livingston Court Extract words starting with capital words from the sentences': company_code ... caps_word_in 0 Abcd ... [Surrey, Avenue] 1 EFGF ... [Bishop, Avenue] 2 zefsalf ... [Golden, Star, Avenue] 3 sdfslew ... [Dunbar, St] 4 zekfsdf ... [West, Livingston, Court] [5 rows x 4 columns]

Python: Tips of the Day
Returns True if there are duplicate values in a flat list, False otherwise
Example:
def tips_duplicates(lst): return len(lst) != len(set(lst)) x = [2, 4, 6, 8, 4, 2] y = [1, 3, 5, 7, 9] print(tips_duplicates(x)) print(tips_duplicates(y))
Output:
True False
