Simple Diamond Pattern in Python
Last Updated :

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
size = 8
spaces = size
for i in range(size//2+2):
for j in range(size):
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=" ")
spaces -= 1
print()
|
Output :
* * * * * *
* * * * * * * *
* * * * * *
* * * *
* *
Example 2:
Python3
size = 11
spaces = size
for i in range(size//2+2):
for j in range(size):
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=" ")
spaces -= 1
print()
|
Output :
* * * * * * * * *
* * * * * * * * * * *
* * * * * * * * *
* * * * * * *
