A programmer has written a Python program to calculate how many full 6-pack egg boxes can be filled from a collection of 57 eggs, and how many individual eggs will be left over.

There are three errors in the code.

total_eggs = 57
box_size = 6

# Calculate how many full boxes can be filled
full_boxes = total_eggs / box_size

# Calculate leftover eggs
left_over = total_eggs // box_size

# Output the results
print("Full boxes: " + str(full_boxes))
print("Leftover eggs: " + str(leftover))

Amend the code to correct the three errors.
