Windows users

• The binaries for AMD64 will also work on processors that implement the Intel 64 architecture. (Also known as the "x64" architecture, and formerly known as both "EM64T" and "x86-64".)
• There are now "web-based" installers for Windows platforms; the installer will download the needed software components at installation time.
• There are redistributable zip files containing the Windows builds, making it easy to redistribute Python as part of another software package. Please see the documentation regarding Embedded Distribution for more information.

macOS users

• For Python 3.8, we provide one installer: 64-bit-only that works on macOS 10.9 (Mavericks) and later systems.
• Please read the "Important Information" displayed during installation for information about SSL/TLS certificate validation and the running the "Install Certificates.command".

And now for something completely different

Michelangelo: Good evening, your Holiness.
Pope: Evening, Michelangelo. I want to have a word with you about this painting of yours, "The Last Supper."
Michelangelo: Oh, yeah?
Pope: I'm not happy about it.
Michelangelo: Oh, dear. It took me hours.
Pope: Not happy at all.
Michelangelo: Is it the jellies you don't like?
Pope: No.
Michelangelo: Of course not, they add a bit of color, don't they? Oh, I know, you don't like the kangaroo?
Pope: What kangaroo?
Michelangelo: No problem, I'll paint him out.
Pope: I never saw a kangaroo!
Michelangelo: Uuh... he's right in the back. I'll paint him out! No sweat, I'll make him into a disciple.
