Shopping List Introduction

At 4:30ish in the Shopping List Introduction video I am unclear as to what Kenneth is doing. He talks about using a simple prompt and uses a single '> ' symbol. Could someone help me out by elaborating on this? What exactly is he doing? Please help!

What you are doing is actually creating a prompt yourself. Back in the day, when you coded in BASIC, whenever a prompt was needed from the user a ">" appeared on screen to the left of the cursor, which indicated that an input was required. This is a reference to BASIC stylization, because he wants us to input("> ") with the text that appears on screen just the "> " prompt. It's not even code, it's just a string. In other words, it could be input("Insert something to buy: ") and the cursor would wait to the right of the colon (:). > is just an abbreviation for input visually on the screen, not a python command or anything.

The prompt can be any text string. The use of "*> *" is an arbitrary example. Whatever string is used as the argument to the input() function will be displayed to the user. Sometimes a specific question can be used as a prompt:

input("What do you need? ")

Yields

What do you need?

The cursor is left at the end of the prompt. A space is often left at the end if the prompt string to leave a visual gap between the prompt and the users input.
