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: Time library
Time library provides lots of time related functions and methods and is good to know whether you're developing a website or apps and games or working with data science or trading financial markets. Time is essential in most development pursuits and Python's standard time library comes very handy for that.
Let's check out a few simple examples:
moment=time.strftime("%Y-%b-%d__%H_%M_%S",time.localtime())
import time time_now=time.strftime("%H:%M:%S",time.localtime()) print(time_now) date_now=time.strftime("%Y-%b-%d",time.localtime()) print(date_now)
