I need a way to make following code working without any ValueError .

You cannot 'make' buggy code work -- except by changing it.
>>> a, b, c, *d = (1,2,3)
>>> d
[]
Why is it necessary to unpack the tuple into arbitrary variables.
It is not necessary.
a_tuple=(1,2,3)
for v in a_tuple:
print v
This is often the right way to access any iterable.
for ctr in range(len(a_tuple)):
print a_tuple[ctr]
This is seldom the right way. See the example below.
Unpacking is for when you have known-length iterables. For instance,
enumerate produces pairs.
>>> for i, v in enumerate('abc'):
print('Item {} is {}.'.format(i, v))
Item 0 is a.
Item 1 is b.
Item 2 is c.
