Pyth

Unlike other popular programming languages out there that include a compiler, Python is considered an interpreted language which entails that the lines of code are passed via an interpreter that has the role of converting them to code at run time.
Considering that Windows does not come with a dedicated Python interpreter embedded, it means that you need to install the actual program in order to run PYscripts. Then again, there are some alternative programs that enable the run of scripts and files without Python.
Pyth is a lightweight utility that enables users to  execute and run scripts without having the main application installed. The application is designed as a console, so it addresses anyone who can work and understand commands and Python. There is no configuration involved and users can start typing scripts and commands right away. It goes without saying that users need to know the basics on how to run Python via commands as well as the programming language itself to get started.
According to the developer, the application allows users to execute PY files without having any external libraries. On the other hand, users can employ built-in Python libraries, according to the needs and preferences of their tasks.
