I am doing sentiment Analysis project. I got the results. I counted the number of positive, neutral and negative.
Here's the code
ltweet.groupby(['sentiment_type'])['sentiment_neutral'].count()
# ltweet= the name of object
# sentiment_type= column
#sentiment_neutral= column
Here;s the output
Out[105]:
sentiment_type
NEGATIVE 280
NEUTRAL 1308
POSITIVE 1193
Name: sentiment_neutral, dtype: int64
I only want to display the 'POSITIVE' only (not negative and neutral)
I tried other codes but still get an error. Can anyone help me with this?
Filter your dataframe first:
ltweet.query('sentiment_type == "POSITIVE"')\
.groupby('sentiment_type')['sentiment_neutral'].count()
Have you tried this?
ltweet.groupby(['sentiment_type'])['sentiment_neutral'].count().loc['POSITIVE']
From the documentation: https://pandas.pydata.org/pandas-docs/stable/generated/pandas.Series.loc.html
Here is an alternative way of doing it. Instead of using a group by, you can filter out only the positive sentiments and then count the number of rows
cnt_pos =ltweet[ltweet["sentiment_type"]=="POSITIVE"]["sentiment_type"].count()
For printing purposes
print("POSITIVE {0}".format(cnt_pos))
