Iterate over *args?

Question

I have a script I\'m working on where I need to accept multiple arguments and then iterate over them to perform actions. I started down the path of defining a function and u

Tho get your precise syntax:

def userInput(ItemA, ItemB, *args):
    THIS = ItemA
    THAT = ItemB
    MORE = args

    print THIS,THAT,MORE


userInput('this','that','more1','more2','more3')

You remove the * in front of args in the assignment to MORE. Then MORE becomes a tuple with the variable length contents of args in the signature of userInput

Output:

this that ('more1', 'more2', 'more3')

As others have stated, it is more usual to treat args as an iterable:

def userInput(ItemA, ItemB, *args):    
    lst=[]
    lst.append(ItemA)
    lst.append(ItemB)
    for arg in args:
        lst.append(arg)

    print ' '.join(lst)

userInput('this','that','more1','more2','more3') 

Output:

this that more1 more2 more3
