Pandas: Extract hash attached word from twitter text from the specified column of a given DataFrame

Pandas: String and Regular Expression Exercise-25 with Solution

Write a Pandas program to extract hash attached word from twitter text 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({
    'tweets': ['#Obama says goodbye','Retweets for #cash','A political endorsement in #Indonesia', '1 dog = many #retweets', 'Just a simple #egg']
    })
print("Original DataFrame:")
print(df)
def find_hash(text):
    hword=re.findall(r'(?<=#)\w+',text)
    return " ".join(hword)
df['hash_word']=df['tweets'].apply(lambda x: find_hash(x))
print("\Extracting#@word from dataframe columns:")
print(df)

Sample Output:

Original DataFrame:
                                  tweets
0                    #Obama says goodbye

3                 1 dog = many #retweets
4                     Just a simple #egg
\Extracting#@word from dataframe columns:
                                  tweets  hash_word
0                    #Obama says goodbye      Obama

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:
