Python runs on Windows, Linux/Unix, Mac OS X, and has been ported to the Java and .NET virtual machines.
Python is free to use, even for commercial products, because of its OSI-approved open source license.
Note: to install "pip" for this Python version, use the following commands:
> python3.14 -m ensurepip --altinstall
> python3.14 -m pip install --upgrade pip
And then you should be able to use "pip3.14" normally.
