python 遍历删除

方法1：ok的

  

   

    

     

    
    

     

       a = [1, 2, 3, 4, 5, 6, 7, 8]
     
    
   

    

     

    
    

     
 # print(id(a))
     
    
   

    

     

    
    

     
 # print(id(a[:]))
     
    
   

    

     

    
    

     
 for i in a[:]:
     
    
   

    

     

    
    

     
 if i > 5:
     
    
   

    

     

    
    

     

       a.remove(i)
     
    
   

    

     

    
    

     

       print(a)
     
    
   

    

     

    
    

     
 # print(id(a))
     
    
  
 

2.filter

内建函数filter()官方文档参考：https://docs.python.org/3/library/functions.html#filter

1. a = [1,2,3,4,5,6,7,8]

2. b = filter(lambda x: x>5,a)

3. print(list(b))

运行结果：

3.列表解析

1. a = [1,2,3,4,5,6,7,8]

2. b = [i for i in a if i >5]

3. prin
