Warning
At the request of the 42 Network, this repository no longer contains the real Rank 03 exam subjects or solutions. The PracticeShell now uses original exercises. They are great for training, but they are not the actual exam questions.
This repository is a growing bank of exercises for the topics learned during Milestone 3 of the Python Common Core.
The goal is to help you:
- Train the topics you learned during the milestone
- Review your doubts and find your weak points
- Prepare for the exam by practicing under time and test pressure.
New exercises will be added over time. Each one focuses on a concept learned during this milestone.
Quick Start • Features • Exam Mode • Practice Mode • Solutions
A Python-based PracticeShell simulator inspired by the new 42 School Common Core Rank 03 learning material, combined with a collection of organized solutions grouped by difficulty level.
Clone the repository:
git clone https://github.com/SaraFreitas-dev/42-Python-ExamShell-Rank03
cd 42-Python-ExamShell-Rank03Run the PracticeShell:
python3 practiceshell.pyYou will be presented with the main menu:
[1] Start Exam
[2] Practice Mode
[3] List all exercises
[q] Quit
No dependencies, no setup: just Python 3.
When the PracticeShell starts, it automatically creates an exam_workspace directory.
All exercise files should be created inside this folder. The grader will only validate solutions placed in the generated workspace.
Example:
exam_workspace/
└── py_word_length_sorter.py
Simply create the requested file, implement your solution, and submit it through the PracticeShell interface for automatic evaluation.
The PracticeShell is the core of this repository.
It lets you practice each milestone topic hands-on, with hidden tests and automatic feedback, instead of just reading solutions.
| Grading | Exam experience | Interface |
|---|---|---|
| Automatic grading | Random exercise assignment | Colored terminal UI |
| Hidden test cases | Progressive level system | Score tracking |
| Timeout protection | Exam & practice modes | Time tracking |
| 6 difficulty levels | Rank progression logic | Pure Python |
The workflow:
- Receive a subject
- Create the requested Python file
- Implement the solution
- Submit for grading
- Fix failing tests
- Progress to the next level
Select:
[1] Start Exam
The simulator will:
- Assign exercises automatically
- Increase difficulty after each successful exercise
- Track your score
- Simulate a 3-hour exam session
The simulator uses a progressive difficulty system. To successfully complete the exam you must validate:
6 / 6 exercises
Select:
[2] Practice Mode
Practice Mode allows you to:
- Choose any exercise
- Focus on a specific level
- Submit unlimited times
- Train without time pressure
Solutions are organized by level and include the completed exercises.
solutions/
├── level_1
├── level_2
├── level_3
├── level_4
├── level_5
└── level_6
This makes it easy to study specific difficulty ranges or review previously solved exercises.
⚠️ Try each exercise in the PracticeShell first. Reading solutions before attempting them will not show you where your weak points are.
- Strings and string transformations
- Lists and matrices
- Dictionaries and character counting
- Sorting with custom criteria
- Palindromes and anagrams
- Ciphers and character shifting
- Number conversion (Roman numerals, binary)
- Rotation and merging of lists
- Stacks and balanced structures
- Edge case handling
- Algorithmic thinking
