Python的简单菱形图案

给定一个整数 n，任务是编写一个Python程序来使用循环和数学公式打印钻石。 n 的最小值应大于 4。

例子 ：

For size = 5

  * * *   
* * * * * 
  * * *   
    *  
    
For size = 8

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

For size = 11

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

方法 ：

使用以下步骤：

• 使用两个循环形成 (size/2+2) x size 的工作表。
• 应用 if-else 条件打印星星。
• 对休息空间应用 else 条件。

下面是上述方法的实现：

示例 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()

输出 ：

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

示例 2：

蟒蛇3

# 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()

输出 ：

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