# Python Program To Print Floyd’s Triangle

In this tutorial, we will have a look at a similar program to pattern printing which is commonly known by the name Floyd’s triangle in Python. It is undoubtedly a very common program, you might have heard about this at least once.

## Floyd’s triangle

A Floyd’s triangle is a consecutive series of natural numbers in a right-angled triangle. This is what Floyd’s triangle looks like-

1 2 3 4 5 6 7 8 9 10

## Approach

The way we can approach to this problem could be-

- Input n (number of rows).
- Initialize count as 1 which will be incremented later.
- Use a for loop initialize i from 1 to n+1
- Use a nested for loop initialize j from 1 to i+1.
- Print count with end=” “.
- Increment the value of count by 1.
- print() will change the line.

## Implementation in Python

As we have discussed approach, now we can implement it using a for loop in Python as shown below-

n = int(input("Enter the total Number of Rows : ")) count= 1 for i in range(1, n + 1): for j in range(1, i + 1): print(count, end = ' ') count = count + 1 print()

Enter the total Number of Rows : 5 1 2 3 4 5 6 7 8 9 10 11 12 13 14 15

So we have printed our expected output. We can also use a similar approach using a while loop. The approach is quite similar with a different syntax as-

n = int(input("Enter the total Number of Rows : ")) count= 1 i = 1 while(i <= n): j = 1 while(j <= i): print(count, end = ' ') count = count + 1 j = j + 1 i = i + 1 print()

Enter the total Number of Rows : 7 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

So we have discussed two methods using for loop and a while loop using the similar approach. I hope you liked this tutorial! Thanks for reading!
