mespy 1.1.3

Toolbox Python per l'analisi dei dati di laboratorio

mespy

Documentation: giancarmine-sparso.github.io/mespy

Small Python toolbox for mechanics laboratory data analysis.

mespy started as a set of helper functions that kept reappearing across mechanics lab notebooks and classroom scripts: loading CSV measurements, computing descriptive and weighted statistics, plotting histograms, and running linear fits with uncertainties. The library brings those recurring tasks together into a single typed package with a small public API that is easy to use in notebooks, scripts, and teaching material.

What It Provides

• CSV loading with explicit missing-data policies
• Descriptive and weighted statistics for one-dimensional data
• Histogram plotting for quick exploratory analysis
• Weighted linear fitting with a typed result object
• Clear validation errors instead of silent nan propagation

Public API

The root package exports:

• load_csv
• median
• weighted_mean
• variance
• covariance
• standard_deviation
• histogram
• lin_fit

The root namespace stays intentionally small. Additional public types, such as mespy.fit_utils.LinearFitResult, live in submodules.

Installation

mespy requires Python >= 3.12.

pip install git+https://github.com/giancarmine-sparso/mespy.git

Development Setup

To set up a local development environment:

Unix / macOS

git clone https://github.com/giancarmine-sparso/mespy
cd mespy
make setup

To activate the virtual environment manually:

source .venv/bin/activate

Windows

git clone https://github.com/giancarmine-sparso/mespy
cd mespy
python -m venv .venv
.venv\Scripts\activate
pip install -e ".[dev]"

Documentation

The Sphinx source lives in docs/source, and the generated site is written to docs/build/html.

Build the documentation with:

make docs

The generated site includes both English and Italian outputs, with English as the default landing page. The documentation also includes usage examples for the available functions. Complete usage workflows and notebooks are available in docs/source/examples.
