Translating maths into code: writing the tattoo function in Python

In a previous post I discussed a mathematical function which represents a range of different list-comprehensions and how their output can be visualised. Here I’ll describe in detail how we can evaluate this function on a computer, using the Python programming language as an example. Here is the mathematical notation for the tattoo function $t$ again: $$t(\theta, p) = \left\{ \sum_{k=-1}^{n}e^{\frac{2 \pi i k^p}{\theta}} \mid n \in -1,\dots,\theta \right\}$$ What should we expect from mathematical expressions in code? ...
