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 :

```  * * * * * * * * *
* * * * * * * * * * *
* * * * * * * * *
* * * * * * *
* * * * *
* * *
*          ```
