input: Write a function to take a dictionary of fruits and their quantities as an argument and return a dictionary with the same quantities. The function should iterate through the input dictionary items to create a new dictionary that maps each fruit to its corresponding count. Return the new dictionary containing the counts.
  
  assert item_counts({"apples": 5, "oranges": 6, "bananas": 7})=={"apples": 5, "oranges": 6, "bananas": 7}
  assert item_counts({"lemons": 3, "grapes": 10})=={"lemons": 3, "grapes": 10}
  assert item_counts({})=={}
output: def item_counts(fruits):
      return fruits
