Python, explained simply
Python reads almost like plain English, which makes it easier to learn than many languages.
A lot of AI tools and models are built with it.
If a guide says you need Python, you install it once on your computer. Then the tool can run.
For example, many free AI projects start with a short Python command.
On ITG Now, our free tool guides tell you when a tool needs Python and what to type to check that you have it.
