Python is a general-purpose programming language that is easy to learn and which can help you work faster and integrate systems more efficiently. Python features high-level data structures, as well as an effective approach to object-oriented programming.

Application development and scripting

You can use Python’s intuitive syntax and dynamic typing to effortlessly deploy applications and scripts in a wide variety of areas and operating systems. Hence, you can use Python to create web frameworks and micro-frameworks or advanced content management systems.

What is more, the standard library comes with support for various Internet protocols such as JSON, HMTL, XML, FTP or IMAP, while the Package Index contains numerous useful libraries that can provide HTML parsers, HTTP client libraries or frameworks for asynchronous networking programming.

Science, education and software development

Python can also be used in scientific and numeric computing thanks to SciPy - a collection of packages for science, engineering and mathematics, IPhyton - an interactive shell for work session editing and recording, Pandas - a data analysis and modeling library and the Software Carpentry Course which enables you to acquire the fundamental skills for running bootcamps, scientific computing and reach open-access teaching materials.

What is more, Python can be used for teaching programming to both novices and more experience users. Additionally, Python can be used as support language for app developers and for testing, management and build control.

Extensible programming language

You can easily extend Python with new functions and data types implemented in C++ or C and use it as an extension language for various applications. Moreover, Python is capable to comprehend arrays / lists and other compound data types. You can quickly index, slice and manipulate them using the built-in functions.

You can also use Python to perform various calculations using the expression syntax and the well known operators. On top of that, you can define functions using mandatory and optional arguments, arbitrary argument lists and keyword arguments.
