**Is python free? **
Python is free, which is open source. The profitable way of programming software is that you use it. The more people you use, the more valuable it is.
Note: Python is a high-level scripting language that combines interpretation, compilation, interactivity, and object-oriented.
Python is designed to be very readable. Compared with other languages, English keywords are often used, and some punctuation marks of other languages have a more distinctive grammatical structure than other languages.
Python is an interpreted language: This means that there is no compilation part in the development process. Similar to PHP and Perl languages.
Python is an interactive language: This means that you can execute code directly after a Python prompt.
Python is an object-oriented language: This means that Python supports an object-oriented style or programming technique where code is encapsulated in objects.
Python is a language for beginners: Python is a great language for junior programmers. It supports a wide range of application development, from simple word processing to WWW browsers to games.
Advantages of Python language
As a beginner who is a beginner in python, python is very simple and very suitable for human reading. Reading a good Python program feels like reading English, even though the English requirements are very strict! The pseudo-code nature of Python is one of its greatest advantages. It allows you to focus on solving problems instead of understanding the language itself.
Easy to learn. Although python is written in C language, it discards the very complex pointers in C and simplifies the syntax of python.
Python is one of FLOSS (Free/Open Source Software). Simply put, you can freely distribute copies of this software, read its source code, make changes to it, and use part of it in new free software. Python hopes to see a better person create and improve often.
Portability-Due to its open source nature, Python has been ported to many platforms (it has been modified to allow it to work on different platforms). If you are careful to avoid using system-dependent features, all your Python programs can run on any of the following platforms without modification. These platforms include Linux, Windows, FreeBSD, Macintosh, Solaris, OS/2, Amiga, AROS, AS/400, BeOS, OS/390, z/OS, Palm OS, QNX, VMS, Psion, Acom RISC OS, VxWorks, PlayStation, Sharp Zaurus, Windows CE and even PocketPC, Symbian and Google's Android platform based on Linux!
Inside the computer, the Python interpreter converts the source code into an intermediate form called bytecode, and then translates it into the machine language used by the computer and runs it. In fact, since you no longer need to worry about how to compile programs, how to ensure that the correct libraries are linked and reproduced, etc., all of this makes using Python easier. Since you only need to copy your Python program to another computer, it will work, which also makes your Python program more portable.
Python supports both process-oriented functional programming and object-oriented abstract programming. In a procedure-oriented language, a program is constructed from procedures or just functions of reusable code. In an object-oriented language, programs are constructed from objects composed of data and functions. Compared with other major languages such as C++ and Java, Python implements object-oriented programming in a very powerful and simple way.
Scalability and embeddability. If you need a piece of your key code to run faster or want some algorithms not to be public, you can write part of your program in C or C++, and then use them in your Python program. You can embed Python in your C/C++ program to provide scripting functions to users of your program.
Rich library. The Python standard library is indeed huge. Python has definable third-party libraries that can be used. It can help you deal with various tasks, including regular expressions, document generation, unit testing, threads, databases, web browsers, CGI, FTP, email, XML, XML-RPC, HTML, WAV files, password systems, GUI (Graphical user interface), Tk and other system-related operations. Remember, as long as Python is installed, all these features are available. This is called the "full-featured" philosophy of Python. In addition to the standard library, there are many other high-quality libraries, such as wxPython, Twisted, and Python image libraries.
Python is indeed a very wonderful and powerful language. It reasonably combines high performance with features that make programming simple and interesting.
Canonical code. Python uses forced indentation to make the code extremely readable.
