LangChain - Output ParsersYou want to retry parsing up to 3 times if it fails. Which approach correctly implements this in Langchain?AUse a loop with try-except inside, break on success, retry on failureBCall parser.parse() once and ignore failuresCUse recursion without base case to retry parsingDWrap parser.parse() in try-except but do not loop or retryCheck Answer
Step-by-Step SolutionSolution:Step 1: Understand retry logicRetry means attempting parsing multiple times until success or max tries reached.Step 2: Implement retry with loop and try-exceptLoop with try-except inside allows catching failures and retrying, breaking on success.Final Answer:Use a loop with try-except inside, break on success, retry on failure -> Option AQuick Check:Retries need loop + try-except [OK]Quick Trick: Loop with try-except to retry parsing safely [OK]Common Mistakes:Ignoring failures without retryUsing recursion without stopping conditionNot looping to retry multiple times
