The following is for rolling up your sleeves and getting your hands dirty.

In my Opinion

You will need a real computer to learn Python programming. Tablets, smart phones, web based classes are not sufficient.

I believe the following is the minimum required.

Where to Get Hardware

Ask around, someone may have hardware gathering dust in a closet. Yard sales. Purchase or build.

Hardware, Etc. You Will Need

The hardware (computer) is a testbed. You want to be able to delete everything and start over.

1. computer (I use cheap refurbished computers from Amazon)
2. monitor, keyboard, and mouse
3. monitor-computer cable
4. network cable or WIFI
5. printer/scanner (optional) (I use an inexpensive network connected HP)

Linux OS preferred (Linux it is free - I use Linux Mint)

internet connection (preferably a Local Area Network (LAN) connected to the internet)

Raspberry Pi

The Raspberry Pi is an inexpensive Single Board Computer (SBC).
