This article introduces the knowledge of "introduction of four tools commonly used in Python". In the operation of actual cases, many people will encounter such a dilemma, so let the editor lead you to learn how to deal with these situations. I hope you can read it carefully and be able to achieve something!

Python as an adhesive

Incompatible systems often need to be linked together, and the process needs to be automated. Python supports all the key integration technologies. It also works well with files, protocols, DLLs and COM objects. Python also provides a wide range of libraries to help you get almost any kind of data. It is also a good tool for controlling other suites, managing systems, and controlling the flow of data from other systems.

Operation mode

Python can be run on the command line or interactively, and it also has a graphical integrated environment, so it is quite convenient to develop Python. There are a lot of visual programming software written in Python to implement functions like Delphi.

object-oriented

Python is a true object-oriented language. It even supports exception handling. If you have studied Java, you should be familiar with this. But other scripting languages, such as PHP, don't seem to have it. This makes the writing of the program clearer and does not require a lot of error checking.

Modules and packages

This is more like Java. For Java support, you can learn about JPython. JPython is Python written in Java, which fully supports Java, and in this environment you can freely use Java's class library with Python. The Python language extension can write new neologism modules, such as functions, for Python in C, C++ or Java. Either it is compiled directly with Python, or it is implemented by dynamic library loading.

Someone has also written a tool that can automatically implement function interface encapsulation for Python, which is called SWIG (Simplified Wrapper and Interface Generator), or simple wrapper and interface generator.

Interesting grammar

Guido thinks the syntax of Python is very beautiful. One of the points is that the representation of block statements is not {} pairs or other symbol pairs commonly used in C language, but the abbreviation representation! Interesting. In this regard, Guido's explanation is: first, the use of narrowing notation reduces visual confusion and shortens the program, thus reducing the scope of attention to the basic unit of code; second, it reduces the programmer's freedom, is more conducive to a unified style, and makes it easier to read other people's programs.

The feeling is still good, as far as the C language is concerned, there are several ways to write curly braces after the if sentence, different people like different looks, it is better to unify, will not look awkward. After the definition of each class or function, the * * line can be an explanatory statement without the need for a comment mark at all. Statements followed by block statements should be followed by a colon.

An one-line statement cannot be too long because there is no line Terminator, and a continuation character (\) is used if it is too long. There are also some interesting examples, such as the following comparison processing, in C language: if (2 can be expressed as if in Python (2)

What is Zope?

Zope is an open source Web application server developed in Python, with which you can easily build content management, intranets, portals, and other custom applications.

Highly object-oriented Web development platform, developed in Python language.

It can run on almost all popular operating systems and supports multiple Python languages.

Can be integrated into other popular servers, but also has its own server.

Provides a clear separation of data / logic / representation.

With extensible built-in objects and powerful integrated security modules.

This is the end of the introduction to the four tools commonly used in Python. Thank you for reading. If you want to know more about the industry, you can follow the website, the editor will output more high-quality practical articles for you!
