LabQuiz is a Python package that allows to seamlessly integrate interactive quizzes directly into Jupyter notebooks — useful for labs, tutorials, practical assignments, continuous assessment, and controlled exams.

• 👉🏼 Live version Try it in binder !

It combines:

• ✅ Multiple-choice and numerical questions
• 🧩 Template-based parameterized questions
• 🔁 Configurable number of attempts
• 💡 Hints and detailed feedback
• 📊 Automatic scoring
• 🌐 Optional remote logging (Google Sheets)
• 📈 Real-time monitoring dashboard (if logging)
• 🔐 Integrity checks and anti-tampering mechanisms

And it comes with two optional companion tools:

• ✏️ quiz_editor — Create, edit, encrypt, and export question banks streamlit app | src code
• 📊 quiz_dash — Monitor, correct, and analyze results in real time streamlit app | src code

🚀 Why LabQuiz?

LabQuiz is designed for active learning and controlled assessment in computational notebooks.

It helps instructors:

• Increase student engagement with embedded exercises
• Provide structured feedback during lab sessions
• Monitor progress in real time
• Run controlled tests and exams
• Detect configuration tampering or integrity violations

It helps students:

• Learn through interaction and immediate feedback
• Track their progress
• Work within structured assessment modes

🚠 What LabQuiz Does

Inside your notebook, you can:

• ✅ Add multiple-choice questions (mcq)
• 🔢 Add numerical questions with tolerance (numeric)
• 🧩 Create parameterized template questions
• 🔁 Limit attempts
• 💡 Provide hints and corrections
• 📊 Compute automatic scores
• 🌐 Log all activity to a Google Sheet backend (optional)
• 🔐 Enable exam mode with integrity checks

Example:

from labquiz import QuizLab

quiz = QuizLab(URL, "my_quiz.yml", retries=2, exam_mode=False)
quiz.show("quiz1")

---

📸 Examples

Multiple-choice question (with hints & correction)

Numerical question

Template-based question (dynamic variables)

---

🧩 Question Types, Pedagogical modes, Logging

Question types

LabQuiz supports four types:

Type	Description
mcq	Standard multiple-choice
numeric	Numerical answers with tolerance
mcq-template	Context-dependent MCQ
numeric-template	Context-dependent numerical questions

Template questions allow dynamic evaluation based on runtime variables — ideal for practical lab computations.

Example:

quiz.show("quiz54", a=res1, b=res2)

Variables can also be generated dynamically

quiz.show("quiz54", autovars=True)

The expected solution is dynamically computed using Python expressions.

Pedagogical modes

LabQuiz supports three pedagogical modes:

• Learning mode (hints + correction available, score display)
• Test mode (limited attempts, score display but no correction)
• Exam mode (no feedback, secure logging)

Quizzes are defined in simple YAML format and support

• Logical constraints (XOR, IMPLY, SAME, IMPLYFALSE)
• Bonuses and penalties
• Relative and absolute tolerances
• Variable generation for templates

📊 Remote Logging & Dashboard

All data can be stored in a Google Sheet backend.

LabQuiz can log: Validation events, Parameters, User answers, Integrity hashes... LabQuiz also includes multiple anti-cheating mechanisms (Machine fingerprinting, Source hash verification, Detection of parameter tampering, Optional encrypted question files, Runtime integrity daemon...)

⚙️ Installation

From PyPI

pip install labquiz

From source:

pip install git+https://github.com/jfbercher/labquiz.git

Import:

import labquiz
from labquiz import QuizLab

Instantiate:

quiz = QuizLab(URL, QUIZFILE,
               retries=2,
               needAuthentication=True,
               mandatoryInternet=False)

🛠 Additional Tools

✏️ quiz_editor — Build & Export Question Banks

Creating YAML files manually works — but quiz_editor is intended to makes it easier. It can also be useful outside ob LabQuiz as a general quiz-editor with export capabilities.

Key features:

• Visual question editing (MCQ, numeric, templates)

• Categories & tags

• Variable generation for templates

• Bonus / malus configuration

• Logical constraints (XOR, IMPLY, SAME, etc.)

• One-click export to:

  • ✅ YAML
  • 🔐 Encrypted version
  • 🌍 Interactive HTML (training mode)
  • 📝 HTML exam version (Google Sheet connected)
  • 📄 AMC–LaTeX format (paper exams)

Online version: 👉 https://jfb-quizeditor.streamlit.app/

Install locally:

pip install quiz-editor

📊 quiz_dash — Real-Time Monitoring & Correction

quiz_dash is the companion dashboard for instructors.

It connects to your Google Sheet backend and provides:

• 📈 Live tracking of submissions
• Live class overview
• 👤 Student-by-student monitoring
• 🔍 Integrity checks (mode changes, retries tampering, hash verification)
• ⚖ Adjustable grading weights
• 🔄 Automatic recalculation
• 📥 CSV export of results

Online version: 👉 https://jfb-quizdash.streamlit.app/
