定义变量和赋值就是系统处理内存的过程和问题，这篇文章分别从申请和释放内存两部分讨论

 

一、申请内存

 

python定义一个变量时，会为变量的对象申请一个内存，该变量会存储指向该对象内存中的地址

这样的好处是复用共同内容对象，节省内存空间

In [1]:

name = 'admin'
print("name=", name)

name1 = name
print("name1=", name1)

 

name= admin
name1= admin

In [2]:

name2 = 'admin'
print("name2=", name2)

 

name2= admin

In [3]:

print(id(name), name)
print(id(name1), name1)
print(id(name2), name2)

 

2951857458848 admin
2951857458848 admin
2951857458848 admin

 

如图：定义了name变量，赋值为“admin”，然后将name赋值给name1，则name1拥有了与name相同的值。再定义另一个变量name2，将name2的值设值为“admin”。也就是name，name1和name2值都为“admin”。则系统赋值运行的过程如下：

1.系统会申请一个内存，存放“admin”

2.将name，name1和name2共用“admin”这个内存

In [4]:

name2 = name
print(name == name2)
print(id(name) == id(name2))

 

True
True

In [5]:

name2 = "admin1"
print(id(name), name)
print(id(name2), name2)

print(name == name2)
print(id(name) == id(name2))

 

2951857458848 admin
2951857622744 admin1
False
False

 

上面两块代码验证了在python系统中，变量会共用相同的值的内存。

1.当name2的值与name的值为“admin”时，name2与name对象的内存地址相同。

2.当name2的值改变为“admin1”时，name2对象的内存地址将会改变了¶

 

二、释放内存

 

Python的内存管理主要有三种机制：引入计数机制、垃圾回收机制和内存池机制。

引入技术机制：在python内部，通过引入技术来保持追踪内存中的对象，python内部记录对象有多少个引用，即引用计数，当对象被创建使就创建一个引用计数，当对象不再需要时，这个对象的引用计数为0时，它将被垃圾回收。

垃圾回收机制：当内存中不再使用该内存部分时，垃圾收集器就会把它们清理掉。它会去检查引用计数为0的对象，然后清除其所在的内存的空间。

内存池机制：在Python中，许多时候申请的内存都是小块的内存，这些小块内存在申请后，很快又会被释放，由于这些内存的申请并不是为了创建对象，所以并没有对象一级的内存池机制。这就意味着Python在运行期间会大量地执行malloc和free的操作，频繁地在用户态和核心态之间进行切换，这将严重影响Python的执行效率。为了加速Python的执行效率，Python引入了一个内存池机制，用于管理对小块内存的申请和释放。内存池的概念就是预先在内存中申请一定数量的，大小相等的内存块留作备用，当有新的内存需求时，就先从内存池中分配内存给这个需求，不够了之后再申请新的内存。这样做最显著的优势就是能够减少内存碎片，提升效率。内存池的实现方式有很多，性能和适用范围也不一样。

下面通过三个步骤分析内存管理和释放的过程：

 

步骤1：将name2和name1的值都更变为“admin1”，可以发现，name1和name2的对象都为“admin1”，name1和name2打印出来的对象内存地址都是相同的。而name对象为“admin”，name打印出来的内存地址与另外两个不同。

In [6]:

name2 = 'admin1'

In [7]:

name1 = name2
print(id(name1), name1)
print(id(name2), name2)

print(id(name), name)

2951857622744 admin1
2951857458848 admin

 

步骤2：将name的对象也更变为“admin1”，再从新打印发现name，name1和name2的地址一样了。

In [8]:

name = 'admin1'
print(id(name1), name1)
print(id(name2), name2)
print(id(name),name)

 

2951857622744 admin1
2951857622744 admin1
2951857622744 admin1

 

步骤3：重新申请name并复制为“admin”，打印出来后，发现该步骤中打印的name的对象内存地址与步骤一种打印name的内存地址变得不一样了。

In [9]:

name = 'admin'

print(id(name1), name1)
print(id(name2), name2)
print(id(name),name)

 

2951857622744 admin1
2951857622744 admin1
