input: Write a python function to calculate the total cost of items given their prices and quantities.
  assert calculate_total_cost([10, 20, 30], [1, 2, 3]) == 140
  assert calculate_total_cost([5, 15, 25], [2, 3, 4]) == 155
  assert calculate_total_cost([100, 200, 300], [1, 1, 1]) == 600
output: def calculate_total_cost(prices, quantities):
      return sum(price * quantity for price, quantity in zip(prices, quantities))
