Python Program to print pattern of letter I

Hello everyone! Welcome back to programminginpython.com. 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.

Approach:

• 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 that 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.
