Python Program to print pattern of letter M

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

Print Pattern M – Code Visualization

Task:

Python program to print the pattern of letter M

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 M
  • following are 2 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 column

    column == 0
    Print 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.

        print()


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

if size < 8:
    print("Enter a value minumin of 8")
else:
    print_pattern(size)
