Python Program to print pattern of letter U

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 U. In the previous tutorials, I have shown you the patterns of letters A to T. Here it’s now time for Pattern U. You can check the complete series on letter patterns here.

Print Pattern U – Code Visualization

Task:

Python program to print the pattern of letter U

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 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 column
    column == 0 and row != n-1Print last column
    column == n-1 and row != n-1

    Print last row
    row == n-1 and column != 0 and column != n-1

  • print in remaining all cases.

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

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