25. Extract Hashtags from Twitter Text

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
1                     Retweets for #cash
2  A political endorsement in #Indonesia
3                 1 dog = many #retweets
4                     Just a simple #egg
\Extracting#@word from dataframe columns:
                                  tweets  hash_word
0                    #Obama says goodbye      Obama
1                     Retweets for #cash       cash

3                 1 dog = many #retweets   retweets
4                     Just a simple #egg        egg
