13. Editing and history of interactive inputSome versions of the Python interpreter support editing the current input line and history, similar to what you see in the Korn shell and the GNU Bash shell. This is implemented using the GNU ReadLine Library, which supports EMACS-style and VI-style editing. This library has its own documentation, which I don't repeat here , But the rationale is easy to explain. the interactive editing and history feature

Overview:The future of machine intelligence has become a trend, now the mobile phone can understand English and Mandarin, then my tens of thousands of dialects of the Greater China is also a trend of intelligence, our dialect, although similar to Putonghua, but it is not the same. This may require a new parser to help us.Our interpreter pattern describes how to define a grammar for a simple language, how to represent a sentence in that language, and h

Interpreter mode (interpreter) definitionGiven a language, define a representation of its grammar and define an interpreter that interprets the sentences in the language using that representation.UML Class DiagramRole　　Abstract expression role : declares an abstract interface that all specific expression roles need to implement. This interface is primarily a inte

The interpreter pattern (interpreter), given a language, defines a representation of its grammar, and defines an interpreter that uses that representation to interpret sentences in the language.If a particular type of problem occurs at a sufficiently high frequency, it might be worthwhile to describe each instance of the problem as a sentence in a simple language

Overview: In the future, machine intelligence has become a trend. Now, mobile phones can understand English and Mandarin. The intelligence of tens of thousands of dialects in Greater China may also be a trend. Although our dialects are similar to those in Mandarin, but it is still different. This may require a new syntax analyzer to help us. Our interpreter mode describes how to define a grammar for a simple language, how to represent a sentence in th

"Interpreter Start Mode" The first way to start the interpreter is similar to starting the Unix shell, which interactively reads and executes each command when it is started by the standard input stream of the TTY device to which it is connected, and reads and executes the script from the file when the interpreter starts with a filename or a standard file input s

Gil Global Interpreter LockThe Gil Essence is a mutex, and the same as all mutex nature, is to make the concurrency run into serial, so as to control the same time shared data can only be modified by one task, thus ensuring data securityTo protect the security of different data, a different lock should be added. For example, the IO mode should be multi-threaded (open file, time.sleep, input and output, etc.), and the calculation is related to using mu

Publish the Taiji language interpreter Publish the Taiji language interpreter(Released on July 15, March 29, the first year of Taiji)I first published an interpreter for some of the Taiji language to explain how to run some Taiji language programs.I focus on the Compilation part, but it hasn't been completed yet, but the

Image example:I have a "bubble mm Sutra" with various tips on bubble mm, such as the steps to eat western food and the methods to watch movies. When I am dating mm, I only need to create an interpreter, run the script above.Interpreter mode:Given a language, the interpreter mode can define a representation of its syntax and provide an interpreter at the same time

Interpreter -java.exe -- Linux general technology-Linux programming and kernel information. The following is a detailed description. The Java interpreter can directly explain and execute Java byte code. The specific command line format is as follows: C: \> java options className arguments ClassName must include information about all software packages. Not only the class name itself, but also the class name

Before introducing the method, let's start with the Python interpreter, which, because Python is a dynamically compiled language, differs from a static language such as C + +, Java, or Kotlin, and is executed at run time by compiling the edges of a sentence code. Java, which compiles high-level languages into JVM bytecode in advance, runs directly through the JVM and machine, so it runs much faster than the dynamic compilation language when performing

Whether it is misunderstanding, as long as the distance will be stranded all the so-called beauty, pick up your time, please give you a right to interpret------------HashlinuxWhen we write the Python code, we get a text file that contains the Python code for the .py extension. To run the code, you need the Python interpreter to execute the .py file.Since the entire Python language is open source from spec to inter
