<p>For quick plotting, you can't go wrong with matplotlib.</p>
To be able to use the tools in these videos you'll need to install them first.
python -m pip install numpy matplotlib
From here, to get "hello world" running for matplotlib, just run;
import numpy as np import matplotlib.pylab as plt x = np.linspace(0, 1, 100) y = x ** 2 plt.plot(x, y);
