Creating recursive function

Question

Question Info:

The calculation "a" was

used for loop to calculate the sum of squares of values in this list: 1, 7, 8, 6, 11 (The answer was 271)

Question To Answer:

(1) Create recursive function to do the same calculation a in the above. (The function input will be the list. Each recursion, you are going to send a sub-list with one less item from the list)

I need help doing this in python programming language. 

Answer 1

def SumOfSquares(x):

if len(x)>0:

return x[0]*x[0]+SumOfSquares(x[1:])

else:

return 0

x=[1, 7, 8, 6, 11]

sum = SumOfSquares(x)

print(sum)
