从Python对象的列表中删除对象 [英] Remove object from a list of objects in python

问题描述

在Python中，如何从对象数组中删除一个对象？像这样的：

In Python, how can I remove an object from array of objects? Like this:

x = object()
y = object()
array = [x,y]
# Remove x

我试过 array.remove（），但它只是一个值，而不是数组中的特定位置的作品。我需要能够通过解决其位置删除对象（删除阵列[0] ）

I've tried array.remove() but it only works with a value, not a specific location in the array. I need to be able to delete the object by addressing its position(remove array[0])

推荐答案

在Python中有没有数组，列表是用来代替。有各种方式来删除列表的对象

In python there are no arrays, lists are used instead. There are various ways to delete an object from a list:

my_list = [1,2,4,6,7]

del my_list[1] # Removes index 1 from the list
print my_list # [1,4,6,7]
my_list.remove(4) # Removes the integer 4 from the list, not the index 4
print my_list # [1,6,7]
my_list.pop(2) # Removes index 2 from the list

在你的情况适当的方法使用的是流行，因为它需要被删除索引：

In your case the appropriate method to use is pop, because it takes the index to be removed:

x = object()
y = object()
array = [x, y]
array.pop(0)
# Using the del statement
del array[0]
