Install

Check installation- type python in cmd

If python had not been installed:

   1–1. Go to python download(For Mac) and download latest stable release(python 3.10.6)
   1–2. Typebrew install python3 at the Terminal prompt
2. After download, type python in cmd and still shows “command cannot found: python”
3. After researching, type python3 in cmd and that works fine!!

failed!!

success!!

Choose IDE

I have VS code experience before, so I choose VS code to be my python IDE.

Use Python interpreter prompt to run python

1. typing python3 and pressing [return] key
2. Once you have started Python, you should see >>> where you can start typing stuff.
3. type print("Hello World") after >>>, and press [return], you will see Hello Worldprinted to the screen.

>>> - This is called the Python interpreter prompt.

python with first step — hello world

You are not allowed to quit the interpreter prompt with normal ctrl + c. You can use ctrl + d or type exit() and press [return] to quit the interpreter prompt.
