Mini-project description-"Guess the number" gameOne of the simplest two-player games is "Guess the number". The first player thinks of a secret number in some known range while the second player attempts to guess the number. After each guess, the first player answers either "Higher", "Lower" or "correct!" depending on whether the secret number I s higher, lower or equal to the guess. In this project, you'll build a simple interactive program in Python

reduces the programmer's freedom and is more conducive to unified style, making it easier to read other people's programs. I think it is good. in C language, there are several kinds of braces behind the if statement. Different people like different things and it is better to unify them. After the definition of each class or function, the first line can be a description statement without the annotator mark. For the statement followed by the block statement, it should be followed by a colon. A ro

Introduction to basic socket programming in Python, pythonsocket In network communication, sockets are almost everywhere. It can be seen as an intermediate software abstraction layer for communications between the application layer and the TCP/IP protocol cluster. It is an interface for two applications to communicate with each other, in addition, the complex TCP

Introduction to the Chapter3 list3.1 What is a list?A list is a series of elements that are arranged in a particular order.bicycle = [' Trek ', ' Cannondale ']Print Bicycle3.1.1 Accessing list elementsPrint (Bicyle[0])3.1.2 Index starting from 0 instead of 1Python provides a special syntax for accessing a list element. You can have Python return the last list element by specifying the index as 1.Print (Bocy

Original works, reproduced please indicate the source: point IPrevious article Python Advanced Programming Generator (Generator) and Coroutine (i): Generator, we describe what is Generator, and write a few examples of using Generator function, this section, We'll introduce Python's coroutine, and there will be a small example, and the next article will introduce

, then numbering each IP packet, ensuring that the other party receives it sequentially, and automatically re-sends if the package is lost. 8) Many of the more advanced protocols are based on the TCP protocol, such as the HTTP protocol for the browser, the SMTP protocol for sending mail, and so on. 9) A TCP message contains both the source and destination IP addresses, the source and destination ports, in addition to the data to be transmitted. 10) What role does the port have? Wh

need to change the source code and recompile, the time wasted, low timeliness, and poor cross-platform.Explanatory: An interpreted language does not require a compiler to compile code, but instead uses an interpreter (or virtual machine) to translate into machine language at run time, once for each execution. Inefficient operation, dependent on the interpreter. The advantage is that because of the use of interpreters, the cross-platform is good, and the explanatory language can dynamically adju

Object oriented into introductionProcess-oriented programmingThe core is the process (pipeline thinking), the process is the steps to solve the problem, the process-oriented design is like a well-designed pipeline, consider when to deal with what things. The main applications are in places where little modification is done, such as the Linux kernel, git, Apache server, etc.Advantages: Greatly reduce the design complexity of the programCons: Poor scalability, change a place is likely to change mu

have not learned the programming language to get started (without any programming language fetters is sometimes a good thing), and ArcGIS has built in arcpy, a development package that uses Python for ArcGIS calls, You can easily invoke all of the Toolbox tools in ArcGIS Desktop and extend it nicely in Python language

internallyCharacteristics:There must be a definite end condition, no end condition will result in exceeding the maximum number of recursive layers (English) error, maximum 999 levelsEvery step deeper, the problem should be less than it was last time.Inefficient, function is called by the stack, may cause stack OverflowIn Python, division by default can be the result of a decimal, and if you want to take an integer, truncate (//) with an int (1/2). ）R

performance to the greatest extent possible, using a lower-level, low-productivity language like C + + is worth it.Python is not an ideal programming language for highly concurrent, multi-threaded applications, because Python has a thing called the GIL (Global Interpreter Lock), which is a mechanism that prevents the interpreter from executing multiple

I. Introduction of Tkinter Tkinter is a Python module, an interface called TCL/TK, which is a cross-platform scripting GUI interface. Tkinter is not the only Python graphics programming interface, but it is one of the more popular ones. The biggest feature is the cross-platform, the disadvantage is the performance is
