从Python对象的列表中删除对象

更新时间:2023-12-04 20:22:58

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]
