Simple Diamond Pattern in Python

Last Updated : 29 May, 2021

Given an integer n, the task is to write a python program to print diamond using loops and mathematical formulations. The minimum value of n should be greater than 4.

Examples :

For size = 5 * * * * * * * * * * * * For size = 8 * * * * * * * * * * * * * * * * * * * * * * * * * * For size = 11 * * * * * * * * * * * * * * * * * * * * * * * * * * * * * * * * * * * * * * * * * * * * *

Approach :

The following steps are used :

Form the worksheet of (size/2+2) x size using two loops.
Apply the if-else conditions for printing stars.
Apply else condition for rest spaces.

Below is the implementation of the above approach :

Example 1:

Python3

# define the size (no. of columns) # must be odd to draw proper diamond shape size = 8 # initialize the spaces spaces = size # loops for iterations to create worksheet for i in range(size//2+2): for j in range(size): # condition to left space # condition to right space # condition for making diamond # else print * if j < i-1: print(' ', end=" ") elif j > spaces: print(' ', end=" ") elif (i == 0 and j == 0) | (i == 0 and j == size-1): print(' ', end=" ") else: print('*', end=" ") # increase space area by decreasing spaces spaces -= 1 # for line change print()

Output :

 * * * * * * * * * * * * * * * * * * * * * * * * * *

Example 2:

Python3

# define the size (no. of columns) # must be odd to draw proper diamond shape size = 11 # initialize the spaces spaces = size # loops for iterations to create worksheet for i in range(size//2+2): for j in range(size): # condition to left space # condition to right space # condition for making diamond # else print ^ if j < i-1: print(' ', end=" ") elif j > spaces: print(' ', end=" ") elif (i == 0 and j == 0) | (i == 0 and j == size-1): print(' ', end=" ") else: print('*', end=" ") # increase space area by decreasing spaces spaces -= 1 # for line change print()

Output :

 * * * * * * * * * * * * * * * * * * * * * * * * * * * * * * * * * * * * * * * * * * * * *
