Variable number of arguments in python

Question

def func(*arg):
    for i in arg:
        print(i)

Here if a user is allowed to enter the arguments using input function (python 3.x).

Eg : "Hello,World,Good,Morning"

If we want each word which is seperated by comma must be passed as argument...

Eg: func("Hello",World","Good","Morning")

How can I solve this problem?

Is there a reason you need this function to take a variable number of arguments, instead of just taking a list of arguments? — abarnert

Use * during function call too. str.split splits the string into a list and then unpack the list items into individual arguments using *.

>>> strs =  "Hello,World,Good,Morning"
>>> spl = strs.split(',')
>>> spl
['Hello', 'World', 'Good', 'Morning']
>>> func(*spl)
Hello
World
Good
Morning
