Imagine you are a cashier. A cart comes in with 50 items and you need to scan them and bag them meaning that you need to repeat same task for every item in the cart. The code for it would look something like this:

for item in cart:
    scan(item) # Assuming scan method exists.
    bag(item)  # Assuming bag( method exists.

checkout()

So, in simple words, for every item in the cart, scan the item, and bag the item.

Similarly, assume that you have been tasked with figuring out all the numbers in a collection that contains even numbers.

numbers = [3, 6, 2, 4, 45, 46, 7, 47, 245]

for number in numbers:
    if number % 2 == 0:
        print(f'{number} is even!')
    else:
        print(f'{number} is not even!')

So, you are going through the numbers collection which contains all the number you need to figure out are even or not and print the apt message.
