For Loop

We use loops if we want to repeat any action n-times.

Look at the example!


              12345
            
# Decreasing prices by 1
prices = [3, 5, 6, 2, 7, 8]

for i in prices:
  print(i, end = ' ')

end = ' ' means that the result will be written in one row (not column).

Look at the table to understand how to minimize the writing of mathematical operators!

Formula	How to minimize
`a = a + 1`	`a += 1`
`a = a - 1`	`a -= 1`
`a = a * 2`	`a *= 2`
`a = a / 2`	`a /= 2`

Завдання

Update subscription prices according to discounts.

Set the for loop to work with the prices using the i iterator.
Set the condition if the element of the list is greater than 30.
Set the 25% discount if the price is greater than 30.
Decrease the i by 3.
Print the prices.
