This repository holds the code for the Real Python How to Get Normally Distributed Random Numbers With NumPy tutorial.

The scripts use NumPy, Matplotlib, and SciPy. You should first create a virtual environment:

$ python3 -m venv venv
$ source venv/bin/activate

You can then install the necessary packages with pip:

(venv) $ python -m pip install numpy matplotlib scipy

Alternatively, you can install from requirements.txt in order to get the same versions of dependencies that were used when developing and testing the code:

(venv) $ python -m pip install -r requirements.txt

Use only one of the pip install commands.

There are four scripts in this repository. The first three—normal_distribution.py, weights.py, and dice.py—show code discussed in the tutorial. The final script, plot_normal_dist.py, contains the code used to generate the first figure in the tutorial.

Each script can be run with python inside your virtual environment:

(venv) $ python normal_distribution.py

You can run the other scripts with a similar command.
