Python Pattern Programs - Floyd's Triangle | Printing Numbers in Right Triangle Shape

In this python pattern video tutorial you will learn how to print numbers in right triangle shape or floyd's triangle program in detail.
Floyd's triangle is the right angle triangle of natural numbers. It contains consecutive numbers starting from 1 at left corner.It is named after Robert Floyd.
Here we are using nested for loop that is for loop within the for loop and logical or operator. In this tutorial we explained how can we write floyd's triangle program in python 3 as well as python 2 in detail.

Yes while printing number pattern we will face problems:)

We can also use format() to solve that.

[@saivikas7032]

Mam,after printing 1st row the for loop for col interrupts. so when we print row 2 so the output should get as 12 naa.
How we are getting output in row 2 as 23

[@AmulsAcademy]

We are taking separate variable to print numbers and we are incrementing that after printing value so we will get continuous numbers :)

[@swaruppanda2842]

what if the input value for n to be written without double codes will it still consider it as string or will take otherwise.

[@AmulsAcademy]

In python 3, input() takes input as string.
if you mention 3, this is the integer value right, but it will treat that as string.

[@krishnansukumar3279]

Thanks a lot for clearly explaining about iterations and rows and columns. Just subscribed.
But I have a doubt. I coded without user input. I added my own range (1,6) for i, and then (1,i+1) for j. Everything else is same as your code.
Now, when count=1 I am getting the output starting from 2. When count=0 I'm getting the proper output starting from 1.
Can you explain why?

[@AmulsAcademy]

Hi,
This code will work properly, check your code with this,
count =1
for i in range(1,6):
for j in range(1,i+1):
print(format(count,"

Can you please explain that when you use more than 2 for loops how can position my print code with respect to for loop I want to print?? I because some Time I don't understand to write my print function exactly under which for loop

[@nicwalsh9537]

Very good tutorial. However, if we wanted to make this a pyramid instead of a right triangle. How would I go about adding in the needed space to form the pyramid?

[@AmulsAcademy]

You need to write the for loop to print space:)
num=int(input("enter the number of rows:"))
n=1
for i in range(num):
for j in range(num-i-1):
print(end=" ")
for j in range(i+1):
print(n,end=" ")
n=n+1
print()
:)

[@Diddin817]

Amuls Academy this left me with a pyramid that starts at 5 and is way longer than 5 rows if my input is 5. Not only that but when it gets to double and triple digits, it is not centered correctly. What could fix this issue?

[@AmulsAcademy]

To solve that 2 digit issue,
num=int(input("enter the number of rows:"))
n=1
for i in range(num):
for j in range(num-i-1):
print(" ", end=" ")
for j in range(i+1):
if n>10:
print(" ",n,end="")
else:
print(" ",n,end=" ")
n=n+1
print()
:)

[@Diddin817]

Amuls Academy as the digits continue to increase to 3 and 4, how will I make sure it all centers correctly

[@AmulsAcademy]

You can use format() for that:)
Just an example:)
print(format(num,"
