Question

6 Generate Triangle Numbers: You must use Python 3

Write a function called generateTriangleNumbers(). This function will take in an integer x and will return a list of integers containing the first x triangle numbers. The nth triangle number is the sum of 1 + 2 + 3 + 4...(n − 1) + n. Some example input-output pairs:

3 -> [1, 3, 6]

1 -> [1]

7 -> [1, 3, 6, 10, 15, 21, 28]

Answer 1

def generateTriangleNumbers(x):
    lst = []
    total = 0
    for i in range(1, x + 1):
        total += i
        lst.append(total)
    return lst


print(generateTriangleNumbers(3))
print(generateTriangleNumbers(1))
print(generateTriangleNumbers(7))
