def abc(array, N):
if array[N] in array:
return array[N-1]**N
else:
return (-1)
print(abc((1,2,3,4,5,6),3))
The result is good up to 5, but why does the result get weird from 6?
python
(1,2,3,4,5,6) Length is 6. And it starts with zero.
That is, a = (1,2,3,4,5,6) a[0] is 1.
It can be accessed from 0 to 5, but if you put 6, it will exceed the access range, so an error will occur.
The format is as follows.
That is, you can put return -1 in the exception.
try:
a = (1,2,3,4,5,6)
...
except IndexError:
# Handle when index is out of bounds
