Python program to print Floyd’s Triangle (3 Ways)

In this program, we will learn how to print Floyd’s Triangle using the Python programming language.

What is Floyd’s Triangle?

We discuss three ways to write code for it.

• Using for Loop
• Using while Loop
• Using Recursion

Python programming code to print Floyd’s Triangle

Using for Loop

Code:-

rows = int(input("Enter the Number of Rows: "))
num = 1

print("Floyd's Triangle") 
for i in range(1, rows + 1):
    for j in range(1, i + 1):        
        print(num, end = ' ')
        num = num + 1
    print()

Using while Loop

Code:-

rows = int(input("Enter the Number of Rows: "))

num = 1
i = 1
print("Floyd's Triangle")
while(i <= rows):
    j = 1
    while(j <= i):        
        print(num, end = ' ')
        num = num + 1
        j = j + 1
    i = i + 1
    print()

Using Recursion

Code:-

def printFloydTriangle(rows):   
    if(rows <= 0):
        return

    for i in range(1, printFloydTriangle.col+1):
        print(printFloydTriangle.num, end=" ")
        printFloydTriangle.num += 1
        
    print()
    printFloydTriangle.col += 1
    rows -= 1
    printFloydTriangle(rows) 

printFloydTriangle.col = 1
printFloydTriangle.num = 1
rows = int(input("Enter the Number of Rows: "))

print("Floyd's Triangle") 
printFloydTriangle(rows)
