creating blank untitled folder

[raseribanez]

firstly I was unable to run this from a command line, it raises errors on line4:

raser@raser85:~$ python crack_zip.py
  File "crack_zip.py", line 4
    if data != '':
     ^
SyntaxError: invalid syntax

When run from IDLE, I also had issues. No errors raised this way, but I had 2 other small issues.
For my test usage I created a folder, entered a txt file inside (containing text) and compressed it into a .zip file, with a password. I then created 'dictionary.txt' with a list of about 10 passwords, including the right one (newline for each word within txt file), and put everything into one directory for testing (crack_zip.py + dictionary.txt + myfile.zip )

Issues were as follows:

1: Returned the last line word of dictionary.txt (when all entries put on same line, all were returned)
2: Was creating an empty 'untitled folder' in my test directory and returning no password

Thanks for this btw, would like to see if we can sort it out
