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
