Mathematical Functions / Sequences in Python Triangular number sequence

In this Python code example, the triangular number sequence is output in a for-loop.

def triangularAlgorithm(n):
    triangular = 0
    for i in range(1, n + 1):
        triangular = triangular + i
        print(triangular)


n = int(input("Enter the quantity of triangular numbers? "))
triangularAlgorithm(n)
Output
Enter the quantity of triangular numbers? 10
