Neutrosophic sets are a type of mathematical object that can be used to model indeterminacy and inconsistent information. They are defined using three degrees of membership: truthfulness, indeterminacy, and falsity. Single-valued Fermatean neutrosophic sets (SVFNSs) and interval-valued Fermatean neutrosophic sets (IVFNSs) are two specific cases of neutrosophic sets that have been shown to be useful in a variety of applications. In this chapter, a new Python toolbox is proposed under the neutrosophic environment, which consists in some Python code for single-valued Fermatean neutrosophic matrices and interval-valued Fermatean neutrosophic matrices. Some definitions of interval-valued Fermatean neutrosophy are vague sets such as union, complement, and intersection, which are presented. Furthermore, the related examples are included.
