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.

I guess you have 25 blank lines at the end of your input file 'unsorted_fruits.txt'

Does unsorted_fruits.txt come from a different os?

test the line endings

import os

padding = 20

file = '/unsorted_fruits.txt'
if os.path.isfile(file):
    if "\r\n" in open(file,"r").read():
        print (file.ljust(padding, " ")," : DOS line endings found")
    if "\n" in open(file,"r").read():
        print  (file.ljust(padding, " "), " : UNIX line endings found")
    if "\r" in open(file,"r").read():
        print (file.ljust(padding, " ")," : MAC line endings found")

No there are no lines on the input file.

Can you share your input file? I don't think it's line-ending issue because in this case it will be extra blank line between other lines.

  unsorted_fruits.txt (Size: 259 bytes / Downloads: 274)
here is the unsorted_fruits txt file.

Testing file.

with open('fruit.txt') as f:
    for line in f:
        print(repr(line))

Output:
'papaya\n'
'\n'
'kiwifruit\n'
'\n'
'zapote blanco\n'
'\n'
'huckleberry\n'
'\n'
'banana\n'
'\n'
'fig\n'
'\n'

So the maker of file have manged to get 2 new line \n between words.
Clean up:

with open('fruit.txt') as f:
    for line in f:
        line = line.strip()
        if line.strip():
            print(line)

Output:
papaya
kiwifruit
zapote blanco
huckleberry
banana
fig
lime
xigua
vanilla

Want a list:

with open('fruit.txt') as f:
    lst = [line.strip() for line in f if line.strip()]

Output:
>>> lst[:10]
['papaya',
 'kiwifruit',
 'zapote blanco',
 'huckleberry',
 'banana',
 'fig',
 'lime',
 'xigua',
 'vanilla',
 'yiessas']
