Program to print window pattern

A window pattern is a visual representation that resembles a window frame using characters like asterisks (*) or plus signs (+). Python makes it easy to create such patterns using loops and string operations.

Simple Rectangular Window

Let's start with a basic rectangular window without any divisions ?

def print_window(n):
    # Print the top row
    print("+" * (2 * n + 1))
    # Print the middle rows
    for i in range(n - 1):
        print("+" + " " * (2 * n - 1) + "+")
    # Print the bottom row
    print("+" * (2 * n + 1))

Window with Cross Dividers

This method creates a window with both horizontal and vertical dividers, resembling window panes ?

def window_with_cross(n):
    if n % 2 != 0:
        center = (n // 2) + 1
        second_center = 0
    else:
        center = (n // 2) + 1
        second_center = (n // 2)
    
    for i in range(1, n + 1):
        for j in range(1, n + 1):
            if i == 1 or j == 1 or i == n or j == n:
                print("*", end=" ")
            else:
                if i == center or j == center:
                    print("*", end=" ")
                elif i == second_center or j == second_center:
                    print("*", end=" ")
                else:
                    print(" ", end=" ")
        print()

Window with Handle

This creates a window pattern with a handle in the middle, simulating a real window ?

def print_window_with_handle(rows):
    # Top border
    print("*" * (2 * rows + 3))
    
    # Upper half
    for i in range(rows):
        print("*" + " " * (2 * rows + 1) + "*")
    
    # Middle row with handle
    print("*" + " " * rows + "||" + " " * rows + "*")
    
    # Lower half
    for i in range(rows):
        print("*" + " " * (2 * rows + 1) + "*")
    
    # Bottom border
    print("*" * (2 * rows + 3))

print_window_with_handle(4)

*         *

*         *

Comparison

Conclusion

Window patterns demonstrate how loops and string operations work together in Python. Start with simple rectangular patterns, then add dividers and handles for more complex designs.
