Visual editor for creating, managing, and exporting LabQuiz question banks.

quiz_editor is a Streamlit-based application designed to help instructors build structured quiz databases for use with LabQuiz — without manually editing YAML files. quiz_editor can also be useful outside of LabQuiz as a general quiz-editor with export capabilities.

It supports question authoring, template variable simulation, encryption, tagging, and export to multiple formats.

Why quiz_editor?

While LabQuiz uses YAML files for defining quizzes, editing them manually can become tedious for large question banks.

quiz_editor provides:

• A visual interface for question creation
• Support for multiple question types
• Built-in encryption & encoding
• Export to multiple formats (subset of questions, HTML, AMC-$\LaTeX$)
• Tagging, Categories and filtering system
• Template variable simulators

Installation

From PyPI

pip install quiz-editor

From source

pip install git+https://github.com/jfbercher/labquiz.git#subdirectory=quiz_editor

Launch

An entry-point is provided that allows to simply use

quiz_editor

Or use the hosted version:

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

quiz_editor -- editing a question, with category, tags, choice of question type (multiple choice, numeric, etc.)

quiz_editor -- editing a proposition -- correct or incorrect, hint (tip), answer (displayed during correction), bonus, penalty, etc.

quiz_editor -- example of template usage with potentially external variables, including an editor preview based on automatically generated variables.

quiz_editor -- Export examples (AMC-$\LaTeX$, interactive HTML, HTML-exam)

quiz_editor -- YAML Export with normal/encoded/encrypted options and question-only file

Supported Question Types

• mcq — Multiple choice
• numeric — Numerical with tolerance
• mcq-template — Parameterized MCQ
• numeric-template — Parameterized numeric

Template Variable Simulation

For template questions, quiz_editor allows you to define variable generators (“simulators”) directly in the interface.

Each variable can specify:

• type (int, float, etc.)
• structure (scalar, vector, …)
• engine (e.g., NumPy RNG)
• call (generation function, e.g. integers(0,10,size=1))

This enables:

• Dynamic generation of values
• Testing template behavior before export
• Automatic inclusion of variable definitions in the YAML file
• Consistent export to LabQuiz, HTML, or AMC formats

These simulators make template questions robust and reusable across sessions.

Features

Question Management

• Create / edit / delete questions
• Add categories and tags
• Define logical constraints (XOR, IMPLY, SAME, IMPLYFALSE)
• Configure bonuses and penalties
• Define tolerances for numerical answers
• Template variables simulation: define variable generators directly in the interface, which enable dynamic generation of values in LabQuiz and in HTML, or AMC exports.

Export Options

quiz_editor can export to:

• ✅ YAML (LabQuiz format)
• 🔐 Encrypted version
• 🔎 Base64-encoded version
• 🌍 Interactive HTML (training mode)
• 📝 HTML exam version (Google Sheet connected)
• 📄 AMC–LaTeX format (for paper exams)

This allows reuse of the same question bank across:

• Notebook-based quizzes
• Web-based self-assessment
• Secure online exams
• Paper multiple-choice exams

Integration with LabQuiz

Typical workflow:

1. Create questions in quiz_editor
2. Export encrypted YAML
3. Use file in:

from labquiz import QuizLab
quiz = QuizLab(URL, "questions.yaml")

Part of the LabQuiz ``Ecosystem''
