Intro:
Python dominates interviews for backend, data science, and automation roles.
If you’re preparing for interviews in 2025, these 5 Python questions show up repeatedly.

🔹 1. What are Python’s Key Data Structures?

Lists, Tuples, Sets, Dictionaries.

Interview tip: Be ready to discuss mutability and performance differences.

🔹 2. Explain Python’s GIL (Global Interpreter Lock)

A classic advanced question.

Interview tip: Clarify that GIL limits threads, not processes.

🔹 3. Difference between Shallow Copy and Deep Copy
import copy
a = [[1, 2], [3, 4]]
shallow = copy.copy(a)
deep = copy.deepcopy(a)

Interview tip: Show how shallow copies still reference nested objects.

🔹 4. Explain Decorators in Python

Functions that modify behavior of other functions.

def log(func):
def wrapper():
print("Before call")
func()
print("After call")
return wrapper

🔹 5. How Does Python Handle Memory Management?

Garbage collection, reference counting, gc module.

Interview tip: Mention automatic memory management.

✅ Final Thoughts
