Explanation:-

The value to be printed is same as the row no +1

So the value to printed would be i +1 as i +1 represents row as row starts from 0

Step 1:- Take input for no of row

Step 2:- Start 1st for loop to iterate n+1 no of times for n rows (for no of rows)

Step 3:- Take 2nd for loop to iterate i items in a row (increment j corresponding to i)

Step 4:- Increment the value of i from 1 to n

Step 5:- Stop

Code:-

n=int(input("No of Rows in the pattern: "))

for i in range(1,n+1):

    for j in range(1,i+1):

        print(i,end=" ")

    print()

Output
