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.
