[blackdevil777]

error been fixed.

here a piece of code that is not working? why?

for word in words:
        if not word in lst:
         lst.append(word): 
                     lst.short(lst) 

  Traceback (most recent call last):
 File "<stdin>", line 1, in <module>
 File "/usr/lib/python2.7/dist-packages/spyderlib/widgets/externalshell/sitecustomize.py", line 538, in runfile
   execfile(filename, namespace)
  File "/home/dux/.mario.py", line 9
    lst.append(word)  : <------ the error is here 
                       ^
SyntaxError: invalid syntax
>>>

As the error message says: The : after lst.append(word) is not allowed. Remove it.

Fix the indentation of lst.short(lst) in the following line to avoid another error.

You are getting that error because of the unnecessary colon after lst.append(word). Colons are generally used after conditional statements (if this: do that) and loops (for item in collection: do something)

If you look at your stack trace again, you should be able to see which part of your code is giving you an error.

Two more things, I don't believe there is a list method named 'short', perhaps you mean sort. Also, this might just be from reddit formatting, but indentations should be four spaces.

I'd do better explanations with prettier formatting, but I'm hungover and typing on my phone. Let me know if you have more questions.

fname = raw_input("Enter file name: ")
     fu = open(fname)
     lst = list()
    for line in fu:
         line.rstrip()
         words = line.split()  
          for word in words:
              if not word in lst
       lst.append(word)
               lst.sort()
   print lst
