python data code example

Example 1: python data object

from dataclasses import dataclass

@dataclass
class InventoryItem:
    """Class for keeping track of an item in inventory."""
    name: str
    unit_price: float
    quantity_on_hand: int = 0

    def total_cost(self) -> float:
        return self.unit_price * self.quantity_on_hand

Example 2: python data types

#use syntax: variable = value
#string
string = 'ASCII text'
#integer
integer = 1234567890
#float
floatnum = 123.456
#list(called arrays in other languages)
numlist = [1,2,3,4,5]
#dictionary(called objects in other languages)
dictionary = {'key','value'}
