分享给大家一篇文章，教你怎样用Python画了一棵圣诞树，快来学习。

如何用Python画一个圣诞树呢？

最简单：

  

   

    

     

    
    

     

      height = 
      5
     
    
   

    

     

    
    

     

      ​
     
    
   

    

     

    
    

     

      stars = 
      1
     
    
   

    

     

    
    

     

      for i 
      in range(height):
     
    
   

    

     

    
    

     

          print((
      ' ' * (height - i)) + (
      '*' * stars))
     
    
   

    

     

    
    

     

          stars += 
      2
     
    
   

    

     

    
    

     

      print((
      ' ' * height) + 
      '|')

哈哈哈哈，总有一种骗了大家的感觉。

其实本文是想介绍Turtle库来画圣诞树。
