It does, but it's hardly an egregious amount (my 3.7 install on Win10 has it at 800Kb... though I guess tcl takes up 10MiB =P). For reference, the built in venv module (which I never use cause I'm all about that virtualenv life) is 1MB. The python tests are 20MB, and that ships by default on every python installation.

Like if you were in a resource constrained situation, you would be customizing your python install anyways (if nothing else, getting rid of the docs, the tests, maybe stripping out all but the compiled code...).
