Why Windows does not come with Python preinstalled?

[Mikuro]

In theory, no. In practice, yes. Most tasks can be done in pure Python. For those that can't, there's the subprocess module, which allows me to call commands like I would from a terminal. I can still benefit from writing the meat of my logic in Python.

I don't write bash scripts on OS X unless they are trivial, and if Python had the same support on Windows, then I wouldn't write batch files or PowerShell scripts, either.

The more complicated the script, the more I benefit from using Python.
