# Pure-Python Analysis Example
This repository provides an example analysis script for processing the Delphes outputs produced by the Snowmass MC Prod task force.
## Installation
Using a python3 installation in a virtual environment, e.g.
```
python3 -m venv myenv
source myenv/bin/activate
```
you can install the requirements via
```
python -m pip install -r requirements.txt
```
## Running
Simply run
```
python analysis.py
```
which outputs a histogram using `histoprint`. For one Delphes file, one sees
```
