All I am trying to do is copy the contents of one file, called 'example.txt' and put them into the output file. Here is what I have but nothing happens when I run it. I am probably missing something obvious but can't figure out what.

def fcopy(fileName1,fileName2):
    fileIn=open(fileName1, 'r')
    fileOut=open(fileName2, 'w')
    for word in fileIn.readlines():
        fileOut.write(word)
    fileIn.close()
    fileOut.close()

This is how I call it:

fcopy('example.txt','output.txt')
open('output.txt')

if nothing happens it means that `open` succeeded: it has worked! – Jean-François Fabre Feb 21 '17 at 20:02
Did it copy the content of example to output ? – Tony Tannous Feb 21 '17 at 20:03

`open('output.txt')` does not automatically print the contents of the file to the console, neither does it open an editor to view the contents. – Christian König Feb 21 '17 at 20:04
Your program works fine. Just tested it. As @ChristianKönig said, open doesn't display the content of the file to you. If you want to do that then print each line in `out.txt`. – Tony Tannous Feb 21 '17 at 20:06
Almost there. If you want to see the contents use `.readlines()`. Example: `print(''.join(open('output.txt').readlines()))` – Zroq Feb 21 '17 at 20:08
If you dont want to write your own function then there are already available modules in python, which you can use. – Nilesh Feb 21 '17 at 20:08
that function above does not copy the file but the file _lines_. It means that CR/LF or LF line terminations may be altered in the copy. – Jean-François Fabre Feb 21 '17 at 20:17
@Zroq: `print(open("output.txt").read())` is even simpler – Jean-François Fabre Feb 21 '17 at 20:26
