def sum1(*a): return(sum(i*i for i in a))
def sum2(a): return(sum(i*i for i in a))
a=[1,2,3]
print(sum1(*a), sum2(a))

showed above: the result from sum1() and sum2() is the same. So, what
is the difference between f(a) and f(*a) |

f(a) -> f([1, 2, 3])
f(*a) -> f(1, 2, 3)

try this:
sum1(a)
sum2(*a)
Then re-read the FineManual(tm):
