25 blank lines in my sorted_fruits output list!

[raven61]

25 blank lines in my sorted_fruits output list don't know how to get rid of them! Don't know how they got there!here is my script

# This just gives you a feel that something is happening.
print('Sorting started')

# This defines where the ipnput and output files are
fin = open('unsorted_fruits.txt', 'r')
fout = open('sorted_fruits.txt', 'w')

# This reads the input file
Fruits = fin.readlines()

# This sorts the input file
Fruits.sort()

# This for loop writes the fruits to the sorted_fruits list.
for fruit in Fruits:
        fout.write(fruit)

# This cloes both files.
fin.close()
fout.close()

# This just lets you know that the sorting is finished.
print('Sorting finished')

If you run it the output sorted_fruits.txt file has 25 empty lines and then the list starts. This was for home work but i've already turned it in I just want to know if I can get the lines removed? I can't figure it out.
