socket is closed, the port number that the local side uses for the socket can be reused immediately. In general, it can be reused only after the system has been defined for a period of time. Boolean integer In this section, we use the SO_REUSEADDR option when studying, specifically:S.setsockopt (socket. Sol_socket,socket. so_reuseaddr,1) Here value is set to 1, which means that the SO_REUSEADDR is marked as true, and the operating system releases the port of the server immediately

The pandas of Python is simply introduced and used Introduction of Pandas 1. The Python data analysis Library or pandas is a numpy based tool that is created to resolve data profiling tasks. Pandas incorporates a large number of libraries and standard data models that provide the tools needed to efficiently manipulate large datasets. Pandas provides a number of functions and methods that enable us to proce

Suppose you have a large data set that is very, very large, and cannot be fully stored in memory. This data set has duplicate data, you want to find out how many duplicate data, but the data is not sorted, because the amount of data is too large, so the sort is impractical. How do you estimate how much of the data set contains no duplicates? This is useful in many applications, such as a planned query in a database: The best query plan depends not only on how much data is in total, but also on h

Turn from: Pseudo-computer scientist | Real Yard FarmFirst introduce a simple and very practical tool, that is multiprocessing. Pool. If your task can be solved with YS = map (f, XS), as you probably know, this form is inherently the easiest to parallel, it's really easy to compute this task in parallel in Python. For example, put each number squared:1 ImportMultiprocessing2 3 deff (x):4 returnX *x5 6Co

A simple tutorial on using the sorted () function in Python, pythonsorted Sorting Algorithm Sorting is also a commonly used algorithm in programs. Whether you use Bubble sorting or quick sorting, the core of sorting is to compare the size of two elements. If it is a number, we can directly compare it, but what if it is a string or two dict? It is meaningless to directly compare the mathematical size. Theref

Quick sorting is a basic sorting algorithm. it is quite concise to use Python code, here we will take a look at a simple example of implementing a fast sorting algorithm and removing duplicates in Python: The sorting efficiency is the same as O (N * logN) it is often used because of its high efficiency. The basic idea of this method is: 1. first, extract a numbe

BP algorithm is the foundation and the most important part of neural network. The loss function needs to be adjusted because the gradient disappears or explodes during the reverse propagation of the error. In the lstm, through the sigmoid to achieve three doors to solve the memory problem, in the process of tensorflow implementation, the need for gradient pruning operations to prevent gradient explosion. RNN's BPTT algorithm also has such problems, so the number of steps over 5 steps, memory eff
