✍️ Sample POC Questions & Answers
1. Which asyncio function is the standard entry point for running a top-level coroutine in Python 3.7+?
asyncio.run() creates a new event loop, runs the given coroutine until completion, and then closes the loop — it is the recommended entry point since Python 3.7.
2. What is the primary purpose of a threading.Lock object in Python?
A Lock ensures mutual exclusion — only one thread can acquire the lock at a time, preventing race conditions on shared data.
3. Why is documenting troubleshooting steps important?
Documentation creates a valuable knowledge base, prevents repeating unsuccessful approaches, and provides accountability for changes made during troubleshooting.
4. What method in unittest is used to verify that two values are equal?
`assertEqual(a, b)` checks that `a` and `b` are equal and raises AssertionError if not.
5. Which Python web framework is known for its 'batteries included' philosophy with built-in ORM, admin panel, and authentication?
Django follows a 'batteries included' philosophy, shipping with an ORM, admin interface, authentication, and many other built-in features.
6. Which module is commonly used for debugging in Python?
The `pdb` (Python Debugger) module is Python's standard interactive source code debugger. It allows developers to set breakpoints, step through code execution, inspect variables, and evaluate expressions at runtime. This functionality is crucial for identifying and resolving issues in Python programs.
