Deep introduction to Python Interfaces

This article describes in detail the problems related to the Python interface service. It is very easy to implement a micro HTTP service program. In Python, only one command line is required, this article mainly studies the use of embedded scripts, because most of the scripts currently do not provide a debugging environment as convenient as the Python interface.

The Python interface has all the powerful functions of modern programming languages. The Python standard library is very large and can help developers deal with various tasks, such: graphical user interface, file processing, multimedia, regular expressions, document generation, unit testing, thread, database, network communication, web browser, CGI, FTP, email, XML, HTML, WAV file, password system, Tk, and other system-related operations.

As long as Python is installed, these functions are available in addition to the standard library, there are many other high-quality libraries, such as wxPython, Twisted, and Python graphics libraries. Python is easy to expand and embed. Many standard modules provided by Python support C or C ++ interfaces. Python and C can work together.

It can be embedded into C or C ++ applications. Therefore, the Python language can be used to provide scripting interfaces for applications. Because it supports cross-language development, you can use Python to design conceptual applications, and gradually transplanted to C, do not use C to rewrite the application before use.

Python fans prefer to call it a high-order dynamic programming language because "scripting language" generally refers to a single use of simple programming tasks such as shell scripts, python cannot be compared with programming languages such as JavaScript that can only process simple tasks.

Scalability is a feature of Python as a programming language. New built-in module) can be written in C or C ++. We can also add Python interfaces to existing modules. Python allows you to focus on the program tasks to be implemented by avoiding excessive syntax constraints.

The Python interface is also known as a clear language. The general guiding ideology of its authors when designing it is that there is only one best solution to a specific problem. This is expressed in The python motto "The Zen of Python" written by Tim Peters:

Interestingly, this is exactly the opposite of the central idea of TMTOWTDIThere's More Than One Way To Do It. This seems to be an important reason why people often compare Perl with Python.

The Python language is a clear language. Another meaning is that its authors intentionally design highly restrictive syntaxes to make bad programming habits, such as not indent to the right of the next line of the if statement) cannot be compiled. This intentionally forces programmers to develop good programming habits. One of the most important items is the indentation rule of Python.

The difference between a module and most other languages, such as C) is the boundary of a module, it is determined by the position of the first character of each line in this line, while the C language uses a pair of curly braces {} to clearly define the boundary of the module, is irrelevant to the character position ).

This has caused controversy. Since the birth of a language like C, the Syntactic meaning of the language is separated from the character arrangement, and it has been regarded as a progress of a programming language. But it is undeniable that Python makes the program clearer and more beautiful by forcing programmers to indent all the places where they need to use modules, such as if, for, and function definition.

Python's share in the programming field has been steadily rising. According to the latest data, Python ranks seventh. The first six are Java, C, VB, C ++, PHP, and Perl. As a very young language. The location of Python is quite exciting. As Microsoft incorporates Python into the. Net platform, it is believed that Python will develop more vigorously in the future. Python is likely to become the mainstream language for rapid development on the. Net platform.
