How to Install Python
Install Python 3, then prove it in a terminal. Download from python.org, or use the Microsoft Store / a package manager. On Windows, tick Add Python to PATH when the installer shows it. Without PATH, python is “not found” even after a successful install.
Check: python --version or py --version. You should see 3.x. Then make a venv for each project so Flask packages do not mix with class homework. VS Code or PyCharm only edits and runs — they do not replace install.
Trap: installing, closing the installer, and never checking version. If print works in the IDE but the terminal fails, PATH is wrong. Fix PATH, don’t reinstall blindly.
