# 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-

1. Input n (number of rows).
2. Initialize count as 1 which will be incremented later.
3. Use a for loop initialize i from 1 to n+1
4. Use a nested for loop initialize j from 1 to i+1.
5. Print count with end=” “.
6. Increment the value of count by 1.
7. 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!
