Program to print the perimeter of a square using asterisk in Python

The program is as follows:

 

# Owner : TutorialsInhand Author : Devjeet Roy

size = int(input("Enter the no of rows: "))

for i in range(size):
    for j in range(size):
        if i == 0 or i == size-1 or j == 0 or j == size-1:
            print("*", end=" ")
        else:
            print(" ",end=" ")
    print()

The output of the program is as follows:

 

PS C:\Users\DEVJEET\Desktop\tutorialsInHand> python code.py
Enter the no of rows: 8
* * * * * * * *
*             *
*             *
*             *
*             *
*             *
*             *
* * * * * * * *
PS C:\Users\DEVJEET\Desktop\tutorialsInHand> python code.py
Enter the no of rows: 5
* * * * *
*       *
*       *
*       *
* * * * *

Few important tips about the program

1. First we ask the user to enter the number of rows of the pattern.

2. Then we use nested loops to print the pattern. The nested loops take care of the rows and columns respectively.

3. The asterisks are printed only on the first and last row and first and last column.

4. We use the blank print() statement to get the control to the next line.
