easy📝 Syntax Q12 of 15
Step-by-Step Solution
Solution:
Step 1: Recall StrOutputParser usage pattern
You first create an instance of StrOutputParser, then call its parse() method with the text input.Step 2: Check each option's syntax
parser = StrOutputParser() result = parser.parse(output_text) correctly creates an instance and calls parse(). Options A and B incorrectly call parse() as a class method. parser = StrOutputParser(output_text).parse() incorrectly passes text to constructor which does not accept arguments.Final Answer:
parser = StrOutputParser() result = parser.parse(output_text) -> Option DQuick Check:
Instance then parse() method = C [OK]
Quick Trick: Create parser instance before calling parse() [OK]
Common Mistakes:
- Calling parse() directly on class without instance
- Passing text to constructor incorrectly
- Confusing method call syntax
