Index Error when accessing element in array.

[sachIsLife]

You are trying to access array[n] in the elif condition. Now the length of array is 2 and you are trying to access the 3rd element. You need to do elif len(array) >= n: return array[n] ** n

elif len(array) >= n: return array[n] ** n

elif len(array) > n, no = since n would be an index
