Supposedly, the first small program we get started with is Hello World. Because it is relatively simple, I will not do too much demonstration.
Here is a small program that I wrote. Primarily used to practice Python's basic syntax, as well as getting started.

Main Implementation Functions

• Ask the user to enter their expected spending amount.

• Display existing product information and ask the user to select

• After the user selects the corresponding product label (pay attention to determine whether to exceed the expected amount of consumption, etc.), save to the shopping cart

• Display of cart information and remaining amount after user exits
