Sciris aims to streamline the development of scientific software by making it easier to perform common tasks. Sciris provides classes and functions that simplify access to core libraries of the scientific Python ecosystem (such as NumPy), as well as low-level libraries (such as pickle). Some of Sciris' key features include: ensuring consistent list/array types; allowing ordered dictionaries to be accessed by index; and simplifying parallelization, datetime arithmetic, and the saving and loading of complex objects. With Sciris, users can achieve the same functionality with fewer lines of code, reducing the need to copy-paste recipes from Stack Overflow or follow dubious advice from ChatGPT.
