Your task is to make function, which returns the sum of a sequence of integers.
The sequence is defined by 3 non-negative values: begin, end, step.
If begin value is greater than the end, function should returns 0
Examples
sequenceSum(2,2,2) === 2
sequenceSum(2,6,2) === 12 // 2 + 4 + 6
sequenceSum(1,5,1) === 15 // 1 + 2 + 3 + 4 + 5
sequenceSum(1,5,3) === 5 // 1 + 4
This is the first kata in the series:
- Sum of a sequence (this kata)

def sequence_sum(begin_number, end_number, step):
#your code heredef sequence_sum(begin_number, end_number, step):
return sum([i for i in range(begin_number, end_number+1, step)])
