Re: [pygame] Re: HELP PLEASE: sprite collision - object not iterable error

Hey I'm on my phone so I can't see the example you need help on  
specially, but here is some general help on the subject:
Arguments are the variables passed to a function.

Example:

def getDogYears(name, age, canine=False):
    if not canine:
        age *= 7 # age times 7
    return "%s is %s years old in dog years." % (name, age)

>> samsDogAge = getDogYears('Sam', 5)
>> print samsDogAge
>> "Sam is 35 years old in dog years."

In this case, the arguments for the function getDogYears() are:
-name
-age
-canine (optional)

So the "second argument" would be the subject's age. Also note that by  
using "canine=False", we have set an optional argument. This means  
that, if no 3rd argument is given, the function will automatically set  
the variable to it's assigned default value. (In this case, 'False')

Hope that helps! :)
