Between the parentheses should go the variables you use (if any) when
calling the function. For example:

def sayhello():
    print "Hello"

You don't have any parameters here, so there's nothing between the brackets

def say(word):
    print word

Now there is one parameter, namely word.

def sayboth(word1,word2):
    print word1
    print word2

Here there are two parameters, word1 and word2.

The number of parameters should be the same as the number of
parameters you use when calling the function:

sayhello()
say("One text")
sayboth("One text","Another text")

There is a much used method to make some of the parameters optional,
but we'll not go into that.

To know what is going wrong with your program, I would have to see the
program (or a simplified version of it that still goes wrong) and
preferably also the exact error message you are getting.
