I need to find average of sum of consequtive elements from list.

At first I am given lenght of list,

then list with numbers,

then am given how many test i need to perform(several rows with inputs),

then I am given several inputs to perform tests(and need to print as many rows with results)

every row for test consist of start and end element in list.

My algorithm:

nu = int(input()) # At first I am given lenght of list

numbers = input().split() # then list with numbers

num = input() # number of rows with inputs

k =[float(i) for i in numbers] # given that numbers in list are of float type

i= 0

while i < int(num):

a,b = input().split() # start and end element in list

i += 1

print(round(sum(k[int(a):(int(b)+1)])/(-int(a)+int(b)+1),6)) # round up t0 6 decimals

Example:

Input:

8 - len(list)

79.02 36.68 79.83 76.00 95.48 48.84 49.95 91.91 - list

10 - number of test

0 0 - a1,b1

0 1

0 2

0 3

0 4

0 5

0 6

0 7

1 7

2 7

Output:

79.020000

57.850000

65.176667

67.882500

73.402000

69.308333

66.542857

69.713750

68.384286

73.668333
