taking intersection over a continous range of values in python

Question

I have a domain of values on which I want to take intersection. for example. 0 <= n1 < 2*pi and -pi <= n2 < pi now the n1 intersection n2 would be [0,pi). The ranges of n1 and n2 can be anything. I want to know if there is an easy way to do this. I am currently using nested if-else to do this. I also want to know if their intersection is null if there is no overlap.

Answer 1

In module sympy there is a class Set and several subclasses, including Interval.

from sympy import Interval, Intersection, pi

n1 = Interval.Ropen(0, 2*pi)
n2 = Interval.Ropen(-pi, pi)

n3 = Intersection(n1, n2)

print(n3)
# Interval.Ropen(0, pi)
