QExPy (Queen’s Experimental Physics) is a python 3 package designed to facilitate data analysis in undergraduate physics laboratories. The package contains a module to easily propagate errors in uncertainty calculations, and a module that provides an intuitive interface to plot and fit data. The package is designed to be efficient, correct, and to allow for a pedagogic introduction to error analysis. The package is extensively tested in the Jupyter Notebook environment to allow high quality reports to be generated directly from a browser.

Getting Started

To install the package, type the following command in your terminal or Anaconda shell.

$ pip install qexpy


It's recommanded to use this package in the Jupyter Notebook environment.

import qexpy as q


With a local clone of this repository, if you wish to do development work, run the make prep in the project root directory, or run the following command explicitly:

pip install -r requirements.txt
pip install -e .

This will install pytest which we use for testing, and pylint which we use to control code quality, as well as necessary packages for generating documentation.

Before submitting any change, you should run make test in the project root directory to make sure that your code matches all code style requirements and passes all unit tests.

The following command checks your code against all code style requirements:

pylint qexpy

Navigate to the tests directory, and execute the following command to run all unit tests:

pytest -v --durations=0
