Python Program to print pattern of letter I

Hello everyone! Welcome back to I am continuing with this pattern programming series, here I will tell you how to print the pattern of the letter I. In the previous tutorials, I have shown you the patterns of letters A to H. Here it’s now time for Pattern I. You can check the complete series on letter patterns here.

Python program to print the pattern of letter I


  • Read an input integer for asking the size of the letter using input()
  • Check if the entered number is greater than 8,
    • if yes, call the function print_pattern()
    • else, show a message to enter a number which is greater or equal to 8
  • print_pattern()
    • here we only do two things, print star(*) and print space( ), just writing conditions so the pattern of *‘s and ‘s will display the pattern I
    • following are 3 conditions for printing *’s
      We have 2 loops, an outer loop() for rows, and an inner loop for columns.
    • # Outer for loop
          for row in range(n): 
              # Inner for loop 
              for column in range(n):
        • Print first and last row
          • (row == 0 or row== n-1)
        • Print middle column
          • (column == n //2 )
    • print in remaining all cases.

                print("*", end=" ")
                print(" ", end=" ")

size = int(input("Enter size: \t"))

if size < 8:
    print("Enter a size greater than 8")
