Print Heart Pattern - Python

Last Updated : 12 Jan, 2026

Given an even integer n, the task is to print a heart-shaped pattern using stars (*) and simple loop logic in Python. For Example:

For n = 8, the output is:
* * * *
* * *
* *
* G F G *
* *
* *
* *
*

For n = 14, a larger heart is printed with the same structure.

Code Implementation

This method prints the heart by splitting it into two parts:

  • The upper part creates the two rounded lobes.
  • The lower part creates the pointed bottom and prints GFG at the center.

Stars and characters are printed by checking the row and column positions using simple mathematical conditions.

Python 
n = 8
m = n+1

# loops for upper part
for i in range(n//2-1):
    for j in range(m):
        
        if i == n//2-2 and (j == 0 or j == m-1):
            print("*", end=" ")
            
        elif j <= m//2 and ((i+j == n//2-3 and j <= m//4) \
                            or (j-i == m//2-n//2+3 and j > m//4)):
            print("*", end=" ")
            
        elif j > m//2 and ((i+j == n//2-3+m//2 and j < 3*m//4) \
                           or (j-i == m//2-n//2+3+m//2 and j >= 3*m//4)):
            print("*", end=" ")
            
        else:
            print(" ", end=" ")
    print()

# loops for lower part
for i in range(n//2-1, n):
    for j in range(m):
        
        if (i-j == n//2-1) or (i+j == n-1+m//2):
            print('*', end=" ")
            
        elif i == n//2-1:
            
            if j == m//2-1 or j == m//2+1:
                print('G', end=" ")
            elif j == m//2:
                print('F', end=" ")
            else:
                print(' ', end=" ")
                
        else:
            print(' ', end=" ")
            
    print()

Output

* * * *
* * *
* *
* G F G *
* *
* *
* *
*

Explanation:

  • n sets the size of the heart and m = n + 1 maintains symmetry.
  • The first loop (for i in range(n//2 - 1)) prints the upper curved part using position checks like i + j and j - i.
  • The second loop prints the lower pointed part using diagonals formed by i - j and i + j.
  • When i == n//2 - 1, the text G F G is printed at the center using m//2.
  • print(..., end=" ") keeps proper spacing and alignment.
