input: Write a python function to calculate the total price of items in a list of tuples where each tuple contains an item name and its price.
  assert calculate_total_price([('apple', 0.5), ('banana', 0.75), ('orange', 0.8)]) == 2.05
  assert calculate_total_price([('bread', 1.5), ('milk', 2.0), ('cheese', 3.25)]) == 6.75
  assert calculate_total_price([('pen', 1.2), ('notebook', 2.5), ('eraser', 0.5)]) == 4.2
output: def calculate_total_price(items):
      return sum(price for name, price in items)
