*args_in_python.py

# *args and **kwargs are mostly used in function definitions. *args and **kwargs allow you to pass a variable number of arguments to a 
# function. What does variable mean here is that you do not know before hand that how many arguments can be passed to your function by the 
# user so in this case you use these two keywords

# args is used to send a non-keyworded variable length argument list to the function.
# Here an example to help you get a clear idea:

def test_var_args(f_arg, *argv):
    print "first normal arg:", f_arg
    for arg in argv:
        print "another arg through *argv :", arg

test_var_args('yasoob','python','eggs','test')
