Parse Input and structure the output # Keywords from tweets

Question

I am trying to put all the #keywords from the tweetText into a separate column along with other columns. I have not mentioned other columns as they would only create confusion.

The tweetText which does not have #keywords shall be deleted and those which have shall be fished out and put them in different column.

I am kind of lost in the part where I need to filter the #Keywords from the tweetText.

Input: TweetsID, Tweets (has many more columns)

Code:

key_word = df1[['tweetID', 'tweetText']].set_index('tweetID')['tweetText']

key_word = key_word.dropna().apply(lambda x: eval(x))
key_word = key_word[key_word.apply(type) == dict]

 #I am lost in this section on how to select the hash keywords?   
def get_key_words(x):                                                       
    return pd.Series(x['tweetText'], 

key_word = key_word.apply(get_key_word)

df2 = pd.concat([coords, df1.set_index('tweetID').reindex(coords.index)], axis=1)

df2.to_csv('Turkey_key_word.csv', index=True)

Appreciate the suggestions.

Edit One:

When parsed input in the chosen answer I get some Syntax Errors

Code:

import re
import pandas as pd

df = pd.readcsv('Turkey_Text.csv')
tweet_column = ['tweetText']
for idx in range(len(tweet_column)):
    tweet = tweet_column[idx]
    hashtag_list = re.findall(r('#\w+)', tweet)
    tweet_column[idx] = " ".join(hashtag_list)

print tweet_column[idx]

Error:

File "keyword_split.py", line 9
    tweet_column[idx] = " ".join(hashtag_list)
               ^
SyntaxError: invalid syntax

Answer 1

Use python and regular expressions. It will make your life a lot easier. The regular expression r'#(\w+)'would work well in this instance.

I don't fully understand the flow of your code, since I don't have much experience with searching CSVs with panda, but if you were to isolate the tweet and return a string of the keywords/hashtags to that column by my understanding of conventional python logic, it might look something like this...

import re

for idx in range(len(tweet_column)):
    tweet = tweet_column[idx]
    hashtag_list = re.findall(r('#\w+)', tweet)
    tweet_column[idx] = " ".join(hashtag_list)
