Question

This python program generates or prints rectangular pattern made up of stars up to n lines.

Python Source Code: Rectangular Pattern


# Rectangular pattern in Python

# Reading number of rows and columns
row = int(input("Enter number of rows: "))
col = int(input("Enter number of columns: "))

print("Rectangular pattern is: ")
for i in range(1,row+1):
    for j in range(1,col+1):
        print("*", end="")
    print()

Output: Rectangular Pattern

Enter number of rows: 4
Enter number of columns: 12
Rectangular pattern is:

In this shot, we will discuss how to generate a rectangle pattern using stars in Python. Numerous patterns can be printed using python, once we have a strong grip over the concepts involving loops. Here we will be using simple for loops to generate a rectangle pattern using stars.

Description

To execute a rectangular pattern using Python programming, we will use 2 for loops:

Outer loop: It is used to iterate over the number of rows.
Inner nested loop: It is used to iterate over the number of columns in each row.

Code

Let’s look at the code snippet below.

# Initialising Length and Breadth
rows = 3
columns = 6

# Loop through number of rows
for i in range(rows):
    
    # Loop through number of columns
    for j in range(columns):
        
        # Printing Pattern
        print('*', end = '  ')
    print()

Explanation

In line 2, we take the input for the number of rows.
In line 3, we take the input for the number of columns.
In line 6, we create a for loop to iterate through the number of rows.
In line 9, we create a for loop to iterate through the number of columns.
In lines 12 and 13, we print the pattern.
- The end statement is used to stay on the same line.
- The print() statement is used to move to the next line.

Given height h and width w, print a rectangular pattern as shown in the example below.

Examples:

Input  : h = 4, w = 5
Output : @@@@@
         @   @
         @   @
         @@@@@

Input  : h = 7, w = 9
Output : @@@@@@@@
         @      @
         @      @
         @      @
         @      @
         @      @
         @@@@@@@@

The idea is to run two loops. One for the number of rows to be printed and the other for the number of columns. Print a ‘@’ only when the current row is first or last. OR the current column is first or last.

C++

#include

using namespace std;

void printRectangle(int h, int w)

{

for (int i=0; i

{

cout << "\n";

for (int j=0; j

{

if (i == 0 || i == h-1 ||

j== 0 || j == w-1)

cout << "@";

else

cout << " ";

}

int main()

{

int h = 4, w = 5;

printRectangle(h, w);

return 0;

}

`Java`

class GFG {

static void printRectangle(int h, int w)

{

for (int i = 0; i < h; i++)

{

System.out.println();

for (int j = 0; j < w; j++)

{

if (i == 0 || i == h-1 ||

j== 0 || j == w-1)

System.out.print("@");

else

System.out.print(" ");


            }
        }
    }
    public static void main(String args[])
    { 
        int h = 4, w = 5;
        printRectangle(h, w) ;
    }
}
Python3
def printRectangle(h, w) :
    for i in range(0, h) :
        print ("")
        for j in
range(0, w) :
            if (i == 0 or i == h-1 or j== 0 or j == w-1) :
                print("@",end="")
            else :
                print(" ",end="")
h = 4
w =
5
printRectangle(h, w)



PHP
function printRectangle($h , $w)
{
    for ($i = 0; $i < $h; $i++)
    {
        echo"\n";
        for ($j = 0; $j < $w; $j++)
        {
            if ($i
== 0 || $i == $h - 1 ||
                $j == 0 || $j == $w - 1)
            echo"@";
            else
            echo" ";
        }
    }
}
    $h = 4;
    $w = 5;
    printRectangle($h, $w);
?>
Output
@@@@@
@   @
@   @
@@@@@

How do you print a rectangular pattern?
Algorithm to print rectangular star pattern using loop
Take the number of rows(N) and columns(M) of rectangle as input from user using scanf function. We will use two for loops to print rectangular star pattern. Outer for loop will iterate N times. In each iteration, it will print one row of pattern.
How do I print a python pattern program?
Steps to Print Pattern in Python
Accept the number of rows from a user using the input() function to decide the size of a pattern. Next, write an outer loop to Iterate the number of rows using a for loop and range() function. Next, write the inner loop or nested loop to handle the number of columns.
How do you make a rectangle in Python?
We can create a simple rectangle by defining a function that takes in two integers representing side length and side height. Then we can loop four times, using the forward() function to create a side representing either the length or height, then rotating the cursor 90 degrees with the right() function.
