How do i print this design pattern

February 23, 2023

I am currently trying to code below pattern … but not able to think how the logic need to be defined for it. It is first time where i am not having any clue how to start with it

Expected output :

 1

 2 3

 4 5 6

 7 8 9 10

 11 12 13 14 15

>Solution :

You could use a nested loop. I’ve explained the variable meaning in the comment in the code

# Define the number of rows for the pattern 
#in your question it's 5, but I will test with 6
num_rows = 6

# Create a variable to keep track of the current number (in each row)
current_num = 1

# Loop over each row
for i in range(num_rows):
    # Loop over each number (column) in the current row
    for j in range(i + 1):
        # Print the current number and a space
        print(current_num, end=" ")

        # Increment the current number
        current_num += 1

    # Go to the next line after each row (new line)
    print()

   # 1 
   # 2 3 
   # 4 5 6 
   # 7 8 9 10 
   # 11 12 13 14 15 
   # 16 17 18 19 20 21
