Python program to print the Inverted heart pattern

Let us see how to print an inverted heart pattern in Python.

Example:

Input: 11
Output:

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

Input: 15
Output:
*
***
*****
*******
*********
***********
*************
***************
*****************
*******************
*********************
***********************
*************************
***************************
*****************************
*************  ************
***********    **********
*********      ********
*******        ******

Approach:

1. Determine the size of the heart.
2. Print an inverted triangle with size number of rows.
3. Print the rest of the heart in 4 segments inside another loop.
4. Print the white space right-triangle at the beginning.
5. Print the first trapezium with stars.
6. Print the white space triangle.
7. Print the second trapezium with stars.

Python3

 # determining the size of the heartsize = 15 # printing the inverted trianglefor a in range(0, size):    for b in range(a, size):        print(" ", end = "")    for b in range(1, (a * 2)):         print("*", end = "")     print("") # printing rest of the heartfor a in range(size, int(size / 2) - 1 , -2):     # printing the white space right-triangle    for b in range(1, size - a, 2):          print(" ", end = "")     # printing the first trapezium    for b in range(1, a + 1):         print("*", end = "")     # printing the white space triangle    for b in range(1, (size - a) + 1):         print(" ", end = "")     # printing the second trapezium    for b in range(1, a):         print("*", end = "")     # new line    print("")

Output:
