Discrepancy in Installation Python 3 on Windows

The Working with Python 3 section mentions you should use python3 to launch the Python 3 interpreter, which does not actually work. The Windows distribution provides only python.exe for all versions of Python, and to launch the Python 3 interpreter you need python. This also creates problems if you install both Python 2 and 3—the executables override each other, and only one of the exes is visible at a time through %Path% (what actually is visible depends on the order of the search paths).

AFAIK the official way to deal with this problem is through the py launcher, but that only solves the python.exe problem, not other scripts installed later during the setup (e.g. pip vs pip3), and other global tools (e.g. pipenv). It will affect other parts of the tutorial as well.

从指南的“Working with Python 3”部分开始，查看链接的 Windows Python launcher 文档。检查教程中其他对 Python、pip、pip3 和 pipenv 的引用，然后更新 Windows 特定的指导，使命令和版本选择说明在全文中保持一致。
