glibc 3.2.0 python38-base 3.2.5 Internal Program Version: pyrsistent 0.18.1 Pyrsistent is a number of persistent collections (by some referred to as functional data structures). Persistent in the sense that they are immutable. All methods on a data structure that would normally mutate it instead return a new copy of the structure containing the requested updates. The original structure is left untouched. http://github.com/tobgu/pyrsistent
