Let us see how to print an inverted heart pattern in Python.
Example:
Input: 11
Output:
*
***
*****
*******
*********
***********
*************
***************
*****************
*******************
*********************
********* ********
******* ******

Input: 15
Output:
*

Approach:
- Determine the size of the heart.
- Print an inverted triangle with size number of rows.
- Print the rest of the heart in 4 segments inside another loop.
- Print the white space right-triangle at the beginning.
- Print the first trapezium with stars.
- Print the white space triangle.
- 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:
