from vaderSentiment.vaderSentiment import SentimentIntensityAnalyzer
analyzer = SentimentIntensityAnalyzer
scores = analyzer.polarity_scores('This is great!')
AString input must be a list; fix by wrapping text in []
BWrong import statement; fix by changing module name
CMissing parentheses when creating analyzer instance; fix by adding ()
DMethod polarity_scores does not exist; fix by using analyze_scores
Step-by-Step Solution

  1. Step 1: Check how analyzer is created

    Analyzer is assigned the class itself, missing parentheses to create an instance.

  2. Step 2: Fix by adding parentheses

    Change to SentimentIntensityAnalyzer() to create an object before calling polarity_scores.

  3. Final Answer:

    Missing parentheses when creating analyzer instance; fix by adding () -> Option C

  4. Quick Check:

    Instance creation needs () [OK]
Quick Trick: Remember () to create object instances [OK]
Common Mistakes:
MISTAKES
  • Calling method on class, not instance
  • Incorrect import causing attribute errors
