I'm a CS fresher prepping for Python developer interviews. After weeks of watching tutorials and reading docs, I still couldn't perform under pressure.
So I started building my own practice papers.
What's in each paper
Every paper simulates a real technical interview round:
📖 Verbal questions (Python/Django/SQL concepts)
🐍 Python coding problems
🗄️ SQL query challenges
🏗️ OOP design tasks
🌐 Django/DRF API problems
🔍 10 "Predict the Output" snippets
45 papers. 3 levels.
Level Papers
🟢 Easy 15 papers
🟡 Medium 15 papers
🔴 Advanced 15 papers
The game changer: Predict the Output
I added 450 code snippets across all papers testing list comprehensions and lambda functions.
Example:
python
nums = [1, 2, 3, 4, 5]
result = [{True: "pass", False: "fail"}[x > 3] for x in nums]
print(result)
Can you get it without running it? These questions forced me to actually think in Python instead of just typing and hoping.
My routine
1 paper/day
45 min timer
No IDE, just pen and paper first
Run the code after to check

Everything is public:
📝 45 Python Interview Practice Papers
Practice papers I built for my own Python developer interview prep. Covers everything a fresher needs — from basic Python to Django REST Framework.
📋 What's Inside
| Section | Topics |
|---|---|
| Verbal / Short Answer | Python concepts, Django basics, SQL theory |
| Python Coding | String manipulation, data structures, algorithms |
| SQL Problems | Queries, joins, aggregations, subqueries |
| OOP Design | Class design, inheritance, real-world systems |
| Django / DRF | Models, serializers, viewsets, filters, custom actions |
| Predict the Output | List comprehensions & lambda functions (MCQ + open-ended) |
📊 Difficulty Levels
| Level | Papers | Count |
|---|---|---|
| 🟢 Easy | Papers 1–5, 16–20, 31–35 | 15 |
| 🟡 Medium | Papers 6–10, 21–25, 36–40 | 15 |
| 🔴 Advanced | Papers 11–15, 26–30, 41–45 | 15 |
🎯 How I Used These
- 1 paper per day as a timed practice session
- Started with Easy, moved to Medium, then Advanced
- Used the "Predict the Output" section to test my understanding of Python internals
- Revisited wrong answers…
If you're grinding for interviews, grab a paper and start. That's literally all it takes.
Copy the Medium post directly into medium.com/new-story, and the DEV.to post into dev.to/new (use the markdown editor). 🚀
