Python Program to print pattern of letter W

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 W. In the previous tutorials, I have shown you the patterns of letters A to V. Here it’s now time for Pattern W. You can check the complete series on letter patterns here.

Print Pattern W – Code Visualization

Task:

Python program to print the pattern of letter W

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 U
    • following are 4 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):
        • First Column
          • column == 0
        • Last Column
          • column == n-1
        • Print right-slanting line
          • row == column and row >= n//2
        • Print left-slanting line
          • row+column == n-1 and row >= n//2
    • print in remaining all cases.
