Python Program - Print Floyd's Triangle

Floyd's triangle is named after Robert Floyd and it is a right-angled triangular array of natural numbers. It is created by filling the rows of the triangle with consecutive natural numbers, starting with 1 at the top.

1
2  3
4  5  6
7  8  9  10
11 12 13 14 15

Example:

In the example below, a function called FloydTriangle is defined. It requires one parameter to pass as number of rows in the triangle and prints the given number of rows of Floyd's triangle.

# function for floyd triangle
def FloydTriangle(n):
  value = 1
  for i in range(1, n+1):
    for j in range(1, i+1):
      print(value, end=" ")
      value = value + 1
    print()

# test the code 
FloydTriangle(7)

The above code will give the following output:

1 
2 3 
4 5 6 
7 8 9 10 
11 12 13 14 15 
16 17 18 19 20 21 
22 23 24 25 26 27 28
