Analyze and debug Python utilities

Q: Analyze and debug Python utilities

This question evaluates proficiency in asynchronous Python, I/O streaming, file system pattern matching, and robust CSV data ingestion, focusing on debugging concurrency issues, handling large streams, and implementing path-search utilities.

Q: How do I approach Data Manipulation (SQL/Python) interview questions?

Data Manipulation (SQL/Python) questions require understanding of core concepts and practice. PracHub provides solutions with explanations to help you master data manipulation (sql/python) interviews.

Question

You are given a snippet where a Python helper class repeatedly reads from an HTTP response stream and writes output. (

Infer and articulate the helper class’s purpose and responsibilities; (
Debug a piece of asynchronous Python code that fetches multiple URLs concurrently—identify race conditions, blocking calls in the event loop, and un-awaited coroutines, then propose fixes; (
Implement list_matching_paths(root, pattern) that returns absolute paths of all files under root matching a glob or regex pattern; (
Read a large CSV safely (dialect, encoding, streaming) and compute simple aggregates with attention to memory and error handling.
