Multi-armed banditry in Python with slots

Roy Keyes

22 Aug 2016 - This is a post on my blog.

I recently released slots, a Python library that implements multi-armed bandit strategies. If that sounds like something that won't put you to sleep, then please pip install slots and read on.

Most heatmap tutorials I found online use pyplot.pcolormesh with random sets of
data from Numpy; I just needed to plot x, y, z values stored in lists--without
all the Numpy mumbo jumbo. Here I have code to plot intensity on a 2D array, and
I only use Numpy where I need to (pcolormesh expects Numpy arrays as inputs).
'''
import matplotlib.pyplot as plt
import numpy as np

#here's our data to plot, all normal Python lists

I have moved this over to the Tech Interview Cheat Sheet Repo and has been expanded and even has code challenges you can run and practice against!
