Delete newline / return carriage in file output

Question

I have a wordlist that contains returns to separate each new letter. Is there a way to programatically delete each of these returns using file I/O in Python?

Edit

Answer 1

Remove empty lines in the file:

#!/usr/bin/env python
import fileinput

for line in fileinput.input("wordlist.txt", inplace=True):
    if line != '\n':
       print line,

The file is moved to a backup file and standard output is directed to the input file.
