How to use Python programming language to build an intranet, in view of this problem, this article introduces the corresponding analysis and solutions in detail, hoping to help more partners who want to solve this problem to find a more simple and easy way.

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

The Python programming language 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. Language extensions can write new language 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 SWIG (Simplified Wrapper and Interface Generator), or simple wrapper and interface generator.

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. At this point, Guido explains that, first of all, the use of abbreviated representations reduces visual confusion and shortens the program, thus reducing the scope of attention to the basic code unit

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 ones, for example, such as the following comparison treatment, in C language:
