Basically, programming languages split into high-level and low-level. Python is one of the high-level programming languages. Python has libraries for data loading, visualizatio, natural language processing, statistics, image processing and etc. The important python libraries used for data analysis are numpy and pandas.
The history of Python is extremely dramatic. The Python language was developed by Guido van Rossum at Centrum Wiskunde & Informatica (CWI) in the Netherlands. It happened during Christmas as Guido planned to spend his Christmas holiday wisely. Why it is called “Python”? Because Guido was a big fan of the ‘Monty Python’s Flying Circus’, a British comedy series in the 1970s.
The Python language was developed based on the foundation of the ABC languages. Guido believes that the Python language is not a open source and it causes Python has not been widely used despite the ABC language is very powerful.
Based on this consideration, Guido has added in a lot of features that did not exist in the ABC languages such as powerful Python libraries. The Python libraries able to help programmer in linking variety of modules (especially C and C++) together easily. Thus, Python is often called as ‘glue’ language.
To compare with the traditional C, C++, Java, etc., Python has less stringent requirement on the code format. User does not have to spend too much effort in writing codes.
For example, Python does not require a semicolon at the end of every statement.
Open source means that all users can see the source code. The programmer’s code written in Python is open source.
For example, Programmer developed a AAA system and publish online. Then the user able to download all the source code of the system and modify it accordingly to their own requirement.
The Python interpreter and modules are open source. Python users are involved to improve the performance of Python.
|3||Free||Users use Python to develop or distribute their own programs without paying any fees or worrying about copyright issues. Even for commercial usage, Python is free.|
|4||High-level language||Python is high-level language. It is easier to use without worrying about the details. The structure of Languages can be seen in the Figure 1.|
|5||Cross-platforms||Python is an interpreted language that can cross platforms. It able to be used in different types of operating systems.|
|6||Object-oriented programming language||Python is object-oriented programming language. It is a feature that helps in developing huge programs without many restrictions.|
|7||Many modules||Python has many modules thus programmers can use modules to fasten their program development.|

Slow speed is a common program with interpreted languages. Python is slow due to:
a. It “translates” the source code while running
b. It shields many low-level details
|2||Difficult for encryption||Unlike compiled language, source code is compiled into executable programs. Python is interpreted language which runs the source code directly, so it is difficult to encrypt the source code.|
|1||Web application development||
Python is also used for web development despite PHP and JS are still the mainstream language for web development. Python is gaining more momentum especially when Python’s web development framework (such as Django, Flask, TurboGears, etc) becomes mature, thus programmers can develop and manage complex web programs easily.
For example, the mod_wsgi module enables Apache to run web programs which written in Python Language.
The world’s largest video website, Youtube, is also developed using Python.
Python is the mainstream programming language in machine learning, neural networks and deep learning in the field of artificial intelligence.
Currently, the world’s best artificial learning frameworks (such as Google Tensor Flow, Facebook PyTorch, etc.) are developed based on big data analysis and deep learning which using Python programming language.
|3||Web crawler||The Python programming language can be used to write web crawler. Technically speaking, Python provides many tools for writing web crawlers such as urllib, Selenium and BeautifulSoup. It also provides web crawler framework called Scrapy.|
|5||Game development||Currently, most of games use C++ to write high-performance modules such as graphical display, which using either Python or Lua to write the game logic. Lua is simpler and lightweight while Python able to support more features and data types.|
