bookFor 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 = ' ')
copy

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!

FormulaHow to minimize
a = a + 1a += 1
a = a - 1a -= 1
a = a * 2a *= 2
a = a / 2a /= 2

Update subscription prices according to discounts.

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