Function not working

[eglaud]

Hello,

I am creating code that will allow the user to (manually) paste a list of excel cells and return a list that lacks quotation marks and duplicates. I have been wanting to do this on my own, and created code that does this - the only issue is that it's not yet a function, so not very easy to repeat. My code below is having trouble working as a function, when I run the program is skips to the second >>> and when I input my list it selects the second word of the first line, telling me "invalid syntax". I type "halp():" (the function name)and it tells me "invalid syntax", highlighting the colon. Where am I going wrong? Below is my code, and the list of fish species I am using as an input

from collections import OrderedDict #gives us a tool to order the list we create


def halp() :

    Fish = raw_input("Paste excel data: ")  #lets us input our fish species 
    Fi = Fish.split("\n") #creates a list based off our fish species
    Fi = list (OrderedDict.fromkeys(Fi)) #removes duplicates
    print '[%s]' % ', '.join(map(str, Fi)) #removes quotation marks and prints list

I'm not sure what changed, but it's suddenly working!
