examshell-python 0.1.4

Interactive 42-style exam practice shell for Python exercises

examshell-python

Interactive terminal shell for practising 42-style Python exam tasks. Simulates the real exam environment — timed pressure, blind grading, sequential levels — or lets you work through exercises freely in practice mode.

Features

• Two modes — Real (exam simulation) and Practice (free training)
• Automatic grading — grademe runs your solution against test cases and shows a results table
• Multi-language task descriptions — each task is described in EN, DE, FR, ES, IT
• 14 tasks across 6 levels — from easy warm-ups to hard algorithmic challenges
• Clean terminal UI — built with Rich

Installation

Requires Python 3.10+.

pip install examshell-python

Or install from source:

git clone <repo-url>
cd examshell-python
pip install .

Usage

examshell42

On launch you choose a mode:

╭─ Choose your Exam mode ─╮
│ Real mode       (1)     │
│ Practice mode   (2)     │
╰─────────────────────────╯

Real mode

Simulates the actual exam. Tasks are drawn randomly per level. Each correct solution earns +16 points; reach 100 to pass.

Command	Description
grademe	Check your solution
status	Show current task info again
finish	End the exam

Practice mode

Work through all tasks in any order, retry freely, no score pressure.

Command	Description
grademe	Check your solution
list	Show all available tasks
choose	Pick a task by number
skip	Move to the next task
status	Show current task info again
finish	End the practice session

How it works

When a session starts, examshell creates a working directory (exam42/) with two sub-folders:

exam42/
├── subjects/
│   └── <task_name>/
│       ├── <task_name>.en.txt   ← task description + signature + examples
│       ├── <task_name>.de.txt
│       └── ...
└── rendu/
    └── <task_name>/
        └── <task_name>.py       ← put your solution here

Write your solution in rendu/<task_name>/<task_name>.py, then run grademe. The shell imports your file, executes each example against it, and prints a pass/fail table.
