integer object

1. Small integer Object poolIntegers are used extensively in programs, and in order to optimize speed, Python uses a small integer pool of objects to avoid frequent application and destruction of memory space for integers.Python defines small

BackgroundOriginal link: http://blog.csdn.net/ordeder/article/details/25343633Python integer objects are immutable objects, what do you mean? For example, run the following Python statement>>>a = 1023>>>a = 1024>>>b = A>>>c = 1024>>>d = 195>>>e = 195

Location of integer Object Storage in Python, and python integer Object Storage Python integer objects are stored in different locations. Some of them are stored in a certain storage, while others are used to open up space. For the reason of this

There are several ways to create an integer object, not the 3 types described in this bookFrom the source to see the end is called Pyint_fromlong, the book written in the Pyint_fromfloat, need to pay attention to this.So the key reading function

Just beginning to learn python, found a very confusing phenomenon, has been to read the source code only to know: is btrueTo initialize two objects with the same parameters, the result is that the two objects are actually the same object???? You

The Python integer object is stored in a different location, some of which are stored in a store, while others create space when used.To say the reason for this sentence, you can look at the following code:A = 5b = 5A is B # TrueA = 500b = 500A is B

The following small series will give you an analysis of the location of integer Object Storage in Python. I think this is quite good. Now I will share it with you and give you a reference. Let's take a look at the location where Python integer

Analysis on the location of integer Object Storage in Python, and python integer Python integer objects are stored in different locations. Some of them are stored in a certain storage, while others are used to open up space. For the reason of this

#小整数对象池‘‘‘Small integer object is resident memory and will not be deleted from the RecycleIntegers are used extensively in programs, and Python uses a small integer pool of objects to optimize speed, avoiding the frequent application and destruction

The Python integer object is stored in a different location, some of it is pre-allocated memory, it has been stored in memory, and others, when used to open up space. To say the reason for this sentence, you can look at the following code: A = 5

The Python integer object is stored in a different location, some of it is pre-allocated memory, it has been stored in memory, and others, when used to open up space. To say the reason for this sentence, you can look at the following code: A = 5b

The storage location of Python integer objects is different. some objects are stored in a certain storage all the time, while others open up the reason for saying this when using them, you can store Python integer objects in different locations.

I recently started to learn python. In fact, I have been learning python for two or three years. As the first learning record, the question is really difficult .. Go to the topic .. First, the question is thrown: Define Variables 1A = 102B =

It is understood that the storage location of integer objects in Python is different in the storage location of Python integer objects. some of them are pre-allocated memory, which is always stored in the memory, while others, the space is opened up

In Python, the storage location of integer objects is different in the storage location of Python integer objects, some of which are pre-allocated memory, which is always stored in the memory, while others, the space is opened up during use.

Recently want to learn the source of Python, hope to write a series of blog, record while urging themselves to learn.Python Source DirectoryDownload the source code tarball from python.org and unzip, I download is Python2.7.12, after

(1) The program sometimes needs to deal with large integers, and the BigInteger class in the Java.math package provides an integer operation of arbitrary precision, which can be constructed by using:Public BigInteger (String VAL) constructs a

  1. py1_bject --> A simple package of long typedef struct{PyObject_HEADlong ob_ival;} PyIntObject; PyInt_Type --> py1_bject type object. Object-related meta information is actually stored in the type object corresponding to the

The automatic boxing and unpacking is introduced from Java 1.5 to automatically convert the original type value to the corresponding object. The automatic boxing and unpacking mechanism allows us to use primitive types or object types more simply
