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]

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)

Output:
